Fenris Wolf

“Unleashing Ragnarok: Meet Fenris Wolf, the Giant Wolf destined to devour gods!”

Fenris Wolf

In the vast tapestry of Norse mythology, the colossal and fearsome Fenris Wolf stands as a formidable figure of unparalleled strength and terror. With a coat of dark, matted fur, he exudes an aura of raw power, each step causing the ground to tremble beneath his immense paws. His eyes, burning with a fiery intensity, gleam like two orbs of molten gold, betraying an ancient intelligence that seems to peer into the depths of the cosmos.

The Wolf’s monstrous form is a sight to behold—a creature of savage beauty and primal grace. His massive jaws, adorned with sharp, ivory fangs, could snap a ship in two with ease. Enormous muscles ripple beneath his fur, attesting to the immeasurable strength contained within his frame. Around his neck, the gleaming chain of Gleipnir, forged by cunning dwarves, holds him captive, a testament to the gods’ fear of his boundless power.

His demeanor is one of both restraint and seething fury. Despite his captivity, an air of undeniable menace surrounds the wolf, an aura that speaks of the cataclysmic force he could unleash upon the realms if ever set free. A restless hunger simmers in his piercing gaze, and the air around him seems charged with a tangible sense of danger.

Present Tense Bio: Fenris Wolf, the offspring of the trickster Loki and the giantess Angrboda, was fated from birth to play a pivotal role in the events leading up to Ragnarok, the prophesized end of the world. Born with a destiny entwined with cosmic chaos, his existence became a source of trepidation for the gods of Asgard.

Feared for his immense strength and potential to bring about destruction, the gods devised a cunning plan to bind the Wolf. The chains of Gleipnir, thin yet unyielding, ensnared him, forever locking away his cataclysmic power. But even in captivity, Fenris Wolf’s purpose remains clear—to embody the forces of chaos and challenge the gods during the final battle of Ragnarok.

His bound form serves as a constant reminder to the divine realm of the challenges that lie ahead. His actions and motivations are intricately tied to his longing for freedom, to unleash his wrath upon the realms that sought to subdue him. His rage simmers, waiting for the day when the chains will shatter, and he can finally fulfill his cosmic role.

In this unyielding state of imprisonment, his tale echoes through the ages, inspiring both awe and dread in the hearts of gods and mortals alike. As the world approaches the inevitable confrontation of Ragnarok, his presence continues to cast a shadow of uncertainty over the divine realms, a reminder of the eternal struggle between order and chaos.

Through the annals of mythology, Fenris Wolf’s saga will forever endure—a story of untamed power, celestial conflict, and a destiny intertwined with the threads of fate. As the cosmic clock ticks forward, the Wolf awaits the fateful hour when the chains of Gleipnir will fall, and his unleashed fury will usher in the end of days.

  • Fearsome Aura. Creatures within 1 mile of Fenris Wolf’s lair have disadvantage on saving throws against being frightened.
  • Eternal Night. The sun is obscured, creating perpetual twilight within a 5-mile radius of Fenris Wolf’s lair.

Divine Artifact: Gleipnir

Gleipnir, the unyielding chain, is a divine artifact forged by the cunning dwarves. This legendary chain is unbreakable and was specifically created to bind Fenris Wolf. With Gleipnir in place, Fenris Wolf is unable to escape and remains bound until the events of Ragnarok, when it will play a crucial role in the final cosmic battle.


Fenris Wolf, the Bound Devourer, is a powerful and fearsome deity of chaos and destruction. Imprisoned by the cunning dwarves with the divine artifact Gleipnir, its existence is a constant threat to the realms. Its legendary power, strength, and ferocity make it a formidable opponent, capable of unleashing cataclysmic devastation upon its enemies. Its bound nature, however, fuels a desire for revenge and freedom, as it seeks to break the chains that hold it captive and wreak havoc upon the world. Fenris Wolf’s dark legacy, entwined with the prophecy of Ragnarok, ensures that its actions are guided by an enigmatic and ominous purpose, leaving a trail of fear and destruction in its wake.

Epic Monsters: Fenrir (5E)


Epic Monsters: Fenrir (5E) | EN World | Dungeons & Dragons | Tabletop Roleplaying Games

Fenrir is the son of Loki and father of fellow wolves Sköll and Hati, raised in Asgard and fed only by Tyr for the other gods lacked bravery enough for the task. Eventually he grew too big however and rather than let him run amok across the world tree, the Asgardians trick Fenrir into being bound by increasingly heavier chains, encouraging and applauding his strength as he broke them all. When they realized that they had no metal links able to hold him they beseeched the dwarves of Svartálfaheimr to form a chain of unequaled strength. This chain was light and supple however, making Fenrir suspicious of trickery and bringing the realization that the other gods feared him. When they went to bind him in it, he agreed only so long as one of them put their hand into his mouth as a show of trust–once again only Tyr has the mettle for it and after Fenrir failed to break out of the dwarven creation dude loses that hand. Bound and unable to resist, the gods tie the colossal wolf to a giant boulder in the middle of nowhere and jam a sword into his mouth to keep it open, forcing Fenrir to drool so much that he forms a lake while waiting for Ragnarok to break free once more and consume Odin.

The Fenris Wolf is more akin to a force of nature than any sort of ordinary monster. This creature is the offspring of the union between the god Loki and a mortal giantess named Angur-boda. The wolf looks like a timber wolf but is enormous in scale, being 50′ tall at the shoulderand weighs 100 tons. Its eyes betray its evil and inherently destructive nature.

Fenrir, the Fenris wolf, is the son of the Norse deity Loki and a giantess. He bit a hand off Tyr, and it is prophesized that he will swallow Odin at Ragnarok.

This monster once lived in Asgard with the gods due to a technicality in the law which allowed spawn of the gods to roam around freely and unharmed. He spent many years roaming the countryside destroying anything and everything he saw, until the gods decided he could no longer be allowed to go free. The wolf is immensely strong and was unable to break any chain placed around his neck, no matter how strong. Odin commissioned the dwarves to create a magical chain called Gleipner a chain which would not break, and so they did; they forged a golden leash from the roots of a mountain, the noise of a moving cat, and the breath of a fish, and this leash was completely unbreakable.

Although it appears as nothing more than silken ribbon. To date, this is the only binding capable of holding the Fenris wolf, and it is believed that in the time of Ragnarok, it too shall fail.

Thus, the Fenris wolf was imprisoned and held captive. Every now and then, the wolf is able to slips his bonds and travel to Midgard to wreak havoc. This always brings the gods themselves to search for him and devise new ways of trapping him.

Fenrir sired two sons, Hati and Skoll, and is believed to be related to the legendary brachyuruses.

The Fenris wolf can speak Common and can communicate with all wolves

The Fenris wolf frightens even the gods, so no opponent should fail to take him seriously. This monster is destruction personified, and is more than willing to prove it to all takers. He only attacks once per round, but his bite is so devastating that it is all he really needs.

While it prefers to simply grab and swallow anything it encounters, it sometimes likes to toy with its prey, tripping and eventually tearing the victim to shreds.

Augmented Critical (Ex): The Fenris wolf’s bite threatens a critical hit on a natural attack roll of 18–20, dealing triple damage on a successful critical hit. Additionally, the victim must succeed on a DC 76 Fortitude save or lose a hand or foot (Fenris wolf’s choice) A victim who loses a foot falls prone and has its land speed reduced to 5 feet. A severed hand make it impossible for the subject to use objects or cast spells with somatic components. The save DC is Strength-based.

Battle Frenzy (Ex): When the Fenris wolf is reduced to 25% of its total hit points, it gains a +4 inherent bonus to Strength and can make an additional melee attack with its bite each round at a –5 penalty. These benefits cease when the Fenris wolf is healed above 25% of it hit points or reaches zero hit points.

Frightful Howl (Su): As a standard action, the Fenris wolf can emit a howl in a 1-mile-radius spread that affects opponents with fewer Hit Dice or levels than it has. The affected creature must make a successful DC 58 Will save or become shaken. Success indicates that the target is immune to the Fenris wolf’s frightful howl for one day. The save DC is Charisma-based.

Improved Grab (Ex): To use this ability, the Fenris wolf must hit a Huge or smaller opponent with its bite attack. It can then attempt to start a grapple as a free action without provoking an attack of opportunity. If it wins the grapple check, it establishes a hold and can try to swallow the foe the following round.

Savage (Ex): If the Fenris wolf successfully trips an opponent, it latches onto the opponent’s body and tears the flesh. This automatically deals an additional 60d6+110 points of damage. If an opponent goes prone for any reason in an area the Fenris wolf threatens, the Fenris wolf can also savage the victim as a free action (treat as the Fenris wolf’s attack of opportunity for the round), even though it had nothing to do with tripping the foe.

Shockwave (Ex): The Fenris wolf can hurl itself to the ground as a standard action to create a localized Earthquake. All creatures within 100 feet of the Fenris wolf must make DC 76 Reflex saves or fall prone. Structures in the radius take 4d6 points of damage instead. The save DC is Strength-based.

Swallow Whole (Ex): The Fenris wolf can try to swallow a grabbed opponent of Huge or smaller size by making a successful grapple check. Once inside, the opponent takes 24d6+22 points of crushing damage plus 12d6+26 points of acid damage per round from the Fenris wolf’s digestive juices. A swallowed creature can cut its way out by dealing 200 points of damage to the Fenris wolf’s digestive tract (AC 35). Once the creature exits, muscular action closes the hole; another swallowed opponent must cut its own way out. The Fenris wolf’s gullet can hold 2 Huge, 4 Large, 8 Medium, 32 Small, 128 Tiny, or 512 Diminutive or smaller creatures.

Trip (Ex): If the Fenris wolf hits with a bite attack it can attempt to trip its opponent (+38 check modifier) as a free action without making a touch attack or provoking an attack of opportunity. If the attempt fails, the opponent cannot react to trip the Fenris wolf.

Unfetterable (Su): The Fenris wolf is under a continuous freedom of movement effect that cannot be dispelled or suppressed by any means. Only epic-level magic can bind the Fenris Wolf, although a specific item or spell would have to be designed for this purpose (such as magical chain called Gleipner).

Skills: The Fenris wolf has a +10 racial bonus on Hide, Listen, Move Silently, and Spot checks. *It also has a +4 racial bonus on Survival checks when tracking by Scent.


Gleipnir is the bindings that hold the mighty Fenris. Even though it is as thin as a silken ribbon, it is stronger than any iron chain. It was forged by the dwarves, and made of six wondrous ingredients

The sound of a cat’s footfall
The beard of a woman
The roots of a mountain
The sinews of a bear
The breath of a fish
The spittle of a bird

Thus we no longer hear a cat’s footfall, women have no beards, mountains have no roots, bears no sinews, fish no breath, and birds no spittle.

Gleipnir will hold until Ragnarök, when the bindings will break and Fenrir will devour Odin.

Gleipnir (Su): The leash that was constructed by the dwarves to contain the Fenris wolf is said to be unbreakable, and even the wolf cannot break it. This golden rope is as light and thin as silk, but is magically durable and cannot be broken or cut by any manmade or natural weapons, even those of +5 enchantment. The golden leash is resistant to all magic, even that of the gods, and no amount of strength or force will snap or destroy it. The Fenris wolf likes to trick creatures into loosening his bonds, then kills the hapless victim and sets free to rain death and destruction on the mortal world.

Originally appeared in Deities & Demigods (1980).

Currently in the World

In the depths of ancient Norse mythology, a figure of immense power and terror looms large—the mighty Fenris Wolf. From his very creation, he has been destined to play a crucial role in the cosmic events that will shape the fate of gods and mortals alike.

Born of the trickster god Loki and the giantess Angrboda, he emerged into the world as a fierce and colossal beast, his jaws capable of devouring the sun and moon. As he grew, his strength and hunger seemed insatiable, leaving the gods wary of the havoc he could wreak upon the realms.

Throughout the ages, Fenris Wolf’s interactions with the world have been both sparse and profound. In his youth, he roamed the wild lands of Asgard, causing the gods great concern with his uncontrollable might. Fearing the prophecies that spoke of his potential to bring devastation during Ragnarok, the gods decided to bind him.

The gods commissioned the skilled dwarves to forge an unbreakable chain called Gleipnir, deceptively thin but incredibly strong. They then tricked Fenris Wolf into testing the chain’s strength, promising him a demonstration of his might. With a combination of cunning and divine magic, they successfully bound him, securing his immense power.

In the years that followed, his presence remained a looming shadow over the cosmos. As the gods went about their affairs and the mortal realm flourished, his imprisonment served as a constant reminder of the challenges that awaited them during Ragnarok. He became both a symbol of fear and a focal point of hope for those who believed in the gods’ ability to triumph over chaos.

As the 1450s dawned, the world continued to turn, and the gods’ plans and intrigues unfolded. Fenris Wolf, though bound, still held his desires and motivations tightly. His greatest longing was for freedom—to break the unyielding chains of Gleipnir and unleash his fury upon the realms.

Deep within his confinement, Fenris Wolf nursed a burning desire for vengeance against the gods who feared him, whose actions led to his binding. His heart seethed with anger and a thirst for retribution against those who kept him from fulfilling his destiny.

Yet, even in his imprisoned state, Fenris Wolf was not idle. His influence seeped through the cosmos like an ominous undercurrent, affecting the minds of both gods and mortals. His bound form continued to be a source of fascination and dread, with tales of his imprisonment passed down through generations.

In this tumultuous time, Fenris Wolf’s fate and his connection to the divine realms remained as intertwined as ever. The gods knew that his eventual release during Ragnarok would herald a cataclysmic confrontation, a battle that would test their very existence.

As the world hurtled towards the destined apocalypse, Fenris Wolf’s bound form stood as a constant reminder of the fragile balance between order and chaos. He waited in the darkness, a silent and ominous presence, knowing that one day, the chain would break, and he would be free to fulfill his cosmic role.

In the face of this timeless narrative, the gods and the cosmos braced themselves for the inevitability of Ragnarok, where Fenris Wolf’s unleashed fury would become the ultimate test of their divine might and will. Until that fateful day, Fenris Wolf’s story, shrouded in both fear and fascination, would continue to echo through the annals of mythology, forever bound to the threads of destiny.
