Eon XXXIII – Age of Giants (Jurassic)

Eon XXXIII – Age of Giants (Jurassic)

Overview: This introductory page provides a comprehensive overview of the Jurassic Period, setting the stage for the detailed explorations in the subsequent pages. It covers the major geological shifts, climate changes, and the overarching dominance of dinosaurs during this era.

Eon XXXIIIa – Rise of the Giants

Time Frame: 201.3 – 174.1 million years ago
Common Name: The Early Jurassic
Theme: Rebirth, colossi, and the forging of new dominions in the wake of cataclysm.

Overview

In the shadow of annihilation, the world breathes again. Eon XXXIIIa dawns with ash in the sky and molten rivers beneath the surface—a time when the world is broken, reshaped, and claimed by beings of colossal destiny.

The Triassic–Jurassic Extinction Event, whispered in legend as the Burning of the Ley, has ended. The great reptilian empires are gone. The skies scream with elemental unrest. From this chaos, new forces emerge—early dinosaurs, proto-dragons, primordial mammalkin, and most fatefully, the Giants (referring to emerging dinosaur titans), born of stone, storm, and ancestral memory.

Aftermath of the Cataclysm

“The world cracked, the bones of the earth bared, and what survived was not meek, but monstrous.”

The extinction wiped out up to 80% of species. In the legends of druids and lorekeepers, this is attributed not only to tectonic fury, but to the Auradragon Betrayal—a cosmic rupture in the arcane lattice that lit entire ley-lines ablaze.

Consequences:

  • Leyline instability triggers massive volcanic winters and localized mana storms.
  • Elemental zones—regions where fire, acid, cold, or gravity surge unpredictably—form across the continents.
  • Survivors retreat underground, underwater, or adapt rapidly with magic-infused mutations.

New Dominant Lifeforms

Dracoraptor hanigani
Among the first true theropods, Dracoraptor stalks the cooling forests with intelligence in its amber eyes. Believed by some to carry fragments of Auradragon soul, giving it uncanny resistance to elemental zones.

Ichthyosaurs & Plesiosaurs
The oceans teem with marine reptile dynasties. These creatures show signs of psionic awareness, worshipping deep leviathans or titanic elemental deities.

Crocodyliforms & Early Crocodiles
Apex ambush predators re-emerge, particularly near geomantic faults where warm energy sustains plant and prey life.

Mammalsnatmus & Other Mammalkin
Small, warm-blooded survivors form the foundation of sentient mammalian life. Early burrow societies begin worshiping lunar cycles and spirit echoes.

The Rise of the Giants (i.e., the rise of dinosaurs)

“We remember the breath of stone. We are the hands that shape continents.” – Giant Rune-Sage of Garn’Muldorr

The Ur-Giants—a poetic name for the first massive dinosaurs—emerge as dominant forces. Shaped by residual divine forces from the shattered Auradragon and the tectonic birth of new mountains, they become icons of the age.

Traits:

  • Towering frames, often fused with elemental stone, ice, or magma.
  • Possess instinctual memory, echoing the world’s deep rhythms.
  • Carry sigil-like patterns on their hides, visible in geomantic sites.

Culture (Mythic):

  • Described by mammalkin and druids as totemic ancestors.
  • Movement creates faultlines and weather shifts—worshipped as elemental gods.

Intelligent Humanoids Emerging

  • Kobolds
    Active beneath volcanic regions, kobolds serve or worship rogue dragon spirits. Master trapmakers and miners, they carve labyrinths into still-cooling magma tubes.
  • Mammalkin Tribes
    Primitive but intelligent nocturnal beings. Communal and spiritually inclined, they worship the moon and the spirits of extinct titans.
  • Formians (Proto-Queens and Hive-Builders)
    Insectoid survivors from deep-time lineages, living in obsidian colonies. Early hive minds channel elemental pheromancy and arcane pheromones.
  • Brinekin (Sahuagin Precursors)
    Amphibious humanoids with psionic ties to deep-sea leviathans. Rule reef cities and interpret storm-signs through coral-oracle chants.
  • Proto-Lizardfolk (Scaled Kin or “Izzh”)
    Upright bipedal reptiles in volcanic marshes. Use mud-glyphs and ritual fire dances. Fiercely territorial.
  • Xulgath Splinter Clans
    Degenerate or mystical offshoots of ancient xulgath, living in ley-scarred sinkholes. Some hold forgotten divine rites; others descend into madness.
  • Fey Castaways
    Stranded remnants from shattered First Fey Realms. Haunt wild magic zones and whisper of broken courts.
  • Element-Blooded Offshoots (Genasi Precursors)
    Humanoids mutated by exposure to elemental rifts. Often feared for their unstable magic and flaming or misty auras.
  • Gug Wanderers
    Aberrant, tusked outsiders from shattered dreams. Practice flesh-sorcery and mimicry magic in obsidian dens.

Minor Groups:

  • Skulkers: Silent hunters from dusk-choked dead forests.
  • Lanternkin: Bioluminescent fungal-folk who guard memory-gardens.
  • Tarkh (Mirrorfolk): Memory-speaking reflections with obsidian skin.

Geography of a Broken World

  • Pangaea Begins to Shatter: Rifting tears the world into massive proto-continents.
  • The Scorch Rift: A fire-scarred trench said to be where the Auradragon’s heart fell.
  • Sky-Ribs Plateau: Floating landforms hover above a dormant elemental vortex.
  • The Fossil Wastes: Cracked salt flats littered with bones of Triassic behemoths.
  • The Cradle Below: Early Underdark zones where kobolds and Formians compete for arcane relics.

Magical Forces in Flux

  • Wild Magic Zones: Spellcasting here causes uncontrollable side effects.
  • Ley Crystals: Mana solidified into physical gems, used by early sorcerers and beastkin.
  • Sigil Groves: Forests that pulse with ambient spellcraft, sacred to Mammalkin druids.

Legacy & Campaign Use

  • Ancestral Weapons and Relics can be uncovered in giant ruins or ley-buried temples.
  • Forgotten Runes of the Ur-Giants offer boons, curses, or ancient magic beyond modern comprehension.
  • Fey Castaway bargains, Kobold labyrinth vaults, and Brinekin coral oracles provide unique narrative tools.
  • Players might explore these lands via time travel, planar echoes, or fossil-memory visions.

Eon XXXIIIa is a crucible of survival, myth, and mutation—where dinosaurs rise not just as beasts, but as living titans. And across the shattered world, sparks of civilization flicker to life beneath the watchful eyes of stars newly born.

Eon XXXIIIb – The Reptilian Renaissance (Middle Jurassic)

Eon XXXIIIb – The Reptilian Renaissance

Time Frame: 174.1 – 163.5 million years ago
Common Name: The Middle Jurassic
Theme: Flourishing dominance of reptilian megafauna, deepening magical ecologies, and the rise of new ecosystems.

Overview

As the shattered world settles, life rebounds with exuberant diversity. Colossal dinosaurs roam fern-swept plains, conifer forests tower like cathedrals, and the fragmented continents give birth to warm inland seas. The Age of Giants continues—but now, it blossoms.

Where Eon XXXIIIa was chaos and birth through fire, Eon XXXIIIb is growth, dominance, and mythic scale. The great sauropods become symbols of terrestrial majesty. Predatory theropods evolve into cunning apex hunters. In the air, feathered gliders flicker toward avian futures.

Dominant Lifeforms

Sauropods
Titanic herbivores like Brachiosaurus, Apatosaurus, and Diplodocus tower over the landscape. Their migrations carve paths that shape ecosystems, and their sheer size reshapes the balance of landbound life.

Theropods
Cunning carnivores such as Allosaurus rise to dominance. Many develop proto-feathers, vocal hunting strategies, and primal territorial rites.

Avian Precursors
Small, feathered theropods begin gliding between conifers. These early bird-kin—like Anchiornis—are sacred to sky-worshipping tribes who believe them to be messengers of elemental wind spirits.

Marine Reptiles
Ichthyosaurs and plesiosaurs continue to dominate the seas, particularly in the new shallow marine corridors. Bioluminescent subspecies emerge, worshipped by reeffolk as divine emissaries of the deep.

Geographical Shifts

Continental Drift Intensifies
Pangaea fractures into Laurasia and Gondwana, generating massive inland seas, archipelagos, and volcanic island chains. Ocean currents shift, and coastal wetlands teem with new life.

Inland Seas
Warm, shallow oceans flood former lowlands. Coral reefs flourish, spawning new aquatic civilizations and saltwater adaptations.

Verdant Dominance
Conifer forests and fern prairies stretch across the temperate zones, dotted by sigil groves that still pulse with residual leyline magic.

Legacy & Magical Evolution

Ley Flux Stabilizing
Mana storms wane, but areas of ambient wild magic remain. These are now sought after by emergent sorcerer-clans, beast-tamers, and element-blooded cults.

First Avians as Spirit-Touched
Avian precursors are revered in some regions as wind-blessed spirits. Mammalkin druids tell of skyborn totems carrying whispers of the First Fey.

Dinosaur Cults
Some intelligent humanoids begin revering sauropods and theropods as gods or ancestors—engraving their forms into stone, bone, and myth.

Expanding Intelligent Life

Kobolds
Still active beneath the volcanic highlands, kobolds refine their mastery of magma tunnels and molten stone.

  • Serve rogue dragon remnants or elemental echoes.
  • Forge glyph-etched tools and smoke-glass lenses for vision in sulfuric dark.
  • Their trap-labyrinths often intersect ancient Formian hiveways.

Mammalkin Tribes
Nocturnal and deeply spiritual, mammalkin form druidic clans in the coniferous underbrush.

  • Practice moon rites and ancestor-summoning via bone flutes and echo-stones.
  • Begin cultivating early fungi, root herbs, and crystal-infused lichens.
  • Some ally with avian spirits or fey castaways to protect sacred groves.

Formians – Hivebuilders Ascendant
Having survived in volcanic underlands, Formians expand surfaceward.

  • Colonies emerge in uplands, structured around elemental pheromancy.
  • Develop caste-specific minds—warrior, runeweaver, diplomat.
  • Clashes erupt with Lanternkin and proto-lizardfolk over fertile geomantic zones.

Tik’cha (Thri-Kreen Precursors)
In arid plateaus and ley-scorched deserts, insectoid Tik’cha begin carving out a presence.

  • Multi-limbed psi-sensitive hunters and scavengers.
  • Revere ancestral consumption; absorb memory through ritual feasting.
  • Serve as erratic mystics, pathfinders, or mercenaries among other tribes.

Locathah Lineages (Legacy of the Brinekin)
With inland seas forming, Locathah rise from Brinekin roots. Nomadic reef-walkers and shell-singers, they protect sacred coral groves and act as aquatic intermediaries.

  • Develop vibrating shell glyphs for communication.
  • Tensions with psionic Brinekin drive Locathah independence.
  • Trade and ally with coastal mammalkin and fey castaways.

Brinekin (Sahuagin Precursors)
Psionically resonant amphibians from deep-sea trenches.

  • Build reef temples to leviathans and primal tide-beasts.
  • Wield storm-call psionics and sacred coral blasters.
  • Split into zealots and philosophers—one seeking war, the other dreams.

Proto-Lizardfolk (Scaled Kin or “Izzh”)
Rise in volcanic wetlands and river deltas.

  • Practice glyph-lore, lava tattoos, and ritual fire battles.
  • Often opposed to Formian expansion and fiercely guard their hot springs.
  • Some view sauropods as living titans, forming symbiotic herder-warrior castes.

Xulgath Splinter Clans
Degenerated or mystic offshoots of once-mighty underworld xulgath.

  • Those blessed by deep leylines keep divine traditions and psychic song-prayers.
  • Others descend into madness, worshipping volcanic demons or element-warped fossils.
  • Encountered near ley-wound canyons, sinkholes, or obsidian cave sanctuaries.

Fey Castaways
Remnants of the broken First Courts wander wild-magic zones.

  • Appear in dream-glades, fog marshes, or ley-bleed regions.
  • Trade in secrets, illusions, and echo-blessed seeds.
  • May ally with mammalkin, avians, or even Tik’cha mystics.

Element-Blooded Offshoots (Genasi Precursors)
Children of elemental rifts, touched by fire, water, air, or stone.

  • Glow with unstable auras, shifting eyes, and wild voice harmonics.
  • Viewed with awe or fear by mortal tribes.
  • Often drawn to wild magic sites or leyline nexuses for grounding and purpose.

Gug Wanderers
Solitary or clan-based horrors of forgotten origin.

  • Dwell in obsidian dens, ancient fumaroles, or twilight valleys.
  • Practice mimicry, dream-carving, and primal flesh-shaping.
  • Sometimes appear as omens of tectonic shifts or ley ruptures.

Campaign Hooks

  • Sky-Rite Totems from early avians grant aerial boons or lost feather-magic.
  • Sauropod Graveyards conceal ancestral relics, dinosaur-bonded familiars, or dormant spirits.
  • Tik’cha Bone-Monks offer dangerous knowledge of death cycles and psionic ley-hunger.
  • Formian Hive-Vaults may contain pre-hive records—maps, relics, or lost caste-songs.
  • Coral-Runes of the Locathah hold keys to deep-water relics, leviathan bargains, or brinebound portals.

Eon XXXIIIc – The Apex of the Dinosaurs

Time Frame: 163.5 – 145 million years ago
Common Name: The Late Jurassic
Theme: Peak dinosaurian dominance, marine abundance, and the maturation of global ecosystems.

Overview

This is the golden age of the dinosaur dynasties. Eon XXXIIIc marks the apex of reptilian might on land, sea, and air. From the sweeping fern prairies of Gondwana to the island jungles of Laurasia, colossal beasts thunder, glide, and stalk. It is a time of vast herds, titanic hunters, and fledgling fliers. As continental drift accelerates, the world diversifies ecologically and culturally. Intelligence continues to spread in subtle niches, and the ancestors of birds begin their long ascent.

Dominant Lifeforms

  • Sauropods at Peak Scale
    Species like Argentinosaurus and Supersaurus embody the zenith of herbivore gigantism. Towering and migratory, they shape ecosystems through sheer movement and mass.
  • Theropod Apex Predators
    Allosaurus, Torvosaurus, and other massive predators rule the food chains. Packs of smaller raptors shadow their movements, scavenging or swarming prey.
  • First True Birds
    Archaeopteryx and kin bridge the gap between dinosaurs and avians. Gliders become powered fliers. Tribal sky-cults among mammalkin and kobolds speak of wind-born gods.
  • Marine Flourishing
    Oceans teem with life. Ammonites, marine crocodilians, and ichthyosaurs fill every niche. Brinekin cities glitter beneath coral arches, while Locathah defend sunken ley-altars.
  • Complex Plant Life
    Conifers dominate upland forests, but cycads, ginkgoes, and lush fernfields provide abundant flora. Flowering plants begin to stir in isolated glades, drawing the attention of fey and insectkin.

Expanding Civilizations

  • Mammalkin Clans
    Now widespread, mammalkin construct shamanic sanctuaries in mountain valleys and coniferous groves. They chronicle seasons through bone-laced calendars and stargazing rites.
  • Kobold Dynes
    Unified under firebound warlocks or rogue dragon seers, kobolds now experiment with sulfurcraft, obsidian glass, and cave-borne alchemy.
  • Tik’cha Sand-Vaults
    The insectoid Tik’cha claim desert mesas, guarding memory vaults carved into mirrored stone. Psionic priestesses chart ancestral migrations across shifting ley-planes.
  • Formian Dominion Broods
    Surface colonies flourish in the warm highlands. Hive architecture becomes baroque, with caste-chapels and pheromone sanctums devoted to elemental symbiosis.
  • Proto-Lizardfolk Confederations
    In river deltas and boiling marshes, the “Izzh” form shifting alliances. Some tame smaller theropods as companions or guardians.
  • Fey Castaway Enclaves
    With leyflow calmer, castaway fey establish new courts hidden in misted hollows or coral grottos. Their magic entangles with early bird-song and flowering growth.
  • Xulgath Oracles and Blighttribes
    Some rediscover their psychic traditions and forge eerie alliances with theropods and volcanic spirits. Others rot into cults of predation, mutation, and echoing madness.
  • Brinekin Leviathan-Kin
    Their underwater cities now span trenches and reef-chains. Prophets dream of war with surface-borne flamewalkers.
  • Locathah Wavetenders
    Traders, scouts, and reef-binders. Their flowing glyph-chants now contain entire histories, encoded in rhythm and bioluminescence.
  • Element-Blooded Scions
    Genasi-precursors lead pilgrimages to elemental fonts. Volcano-throned flamekin, storm-walking airfolk, and oceanborn mystics gather apprentices and forge new rites.
  • Gug Visionaries
    Some gugs evolve into cryptic loremasters, obsessed with fossil-memory and tectonic dreaming. Others remain ravenous and ruinous.

Magical Currents and Wild Zones

  • Featherstorm Zones
    Where avian precursors gather, ambient wind-magic accelerates mutation and sentience.
  • Fossil Cysts
    Ancient battlefields now sealed in crystal or amber hold memory-echoes of past titans.
  • Reef Thrones
    Psionic coral formations become nexuses for Brinekin prophecy and Locathah diplomacy.
  • Skyroot Arches
    Floating groves of half-magic trees drift between mountain peaks. Fey, mammalkin, and air-blooded commune beneath them.

Campaign Hooks

  • Birdsong Sigils: Early birds possess feathers etched with lost sky-magic.
  • Fossil-Lords: Theropod-bonded warlords uncover living memories of extinct ancestors.
  • Coral Wars: Brinekin and Locathah vie for control of a dreaming leviathan’s shrine.
  • Xulgath Eclipse Ritual: A sun-swallowing prophecy threatens to unseal an elemental god.
  • Gug Amber-Crypts: Deep time relics call out to dreamers and madmen alike.

Eon XXXIIIc is the climax of saurian sovereignty—a world where titans rule, the first birds sing, and mortals stare skyward in awe, or downward into the roots of magic and memory.
