Heimdall — Watchman of the Gods & Guardian of Bifröst
Heimdall is the divine sentinel at heaven’s edge: son of nine mothers, golden-toothed, almost sleepless, able to see by night as clearly as by day and hear grass growing on the earth. From Himinbjörg he guards Bifröst against hostile crossings. When Ragnarök begins, the blast of Gjallarhorn will awaken the gods and announce that the final battle can no longer be delayed.

Divine Mechanics
Heimdall in Play
Heimdall is not built around explosive damage. His power is information, interception and control of passage. He sees hidden movement before it becomes an ambush, hears plans whispered far beyond ordinary range, punishes teleportation and planar crossing, and turns Gjallarhorn into a battlefield-wide alarm that makes surprise nearly impossible for his allies.

Divine Traits
Divine Nature. Heimdall requires no air, food or drink. He sleeps only by choice and never needs more than a few moments of rest.
Intermediate Deity — Divine Rank 15. Lower-rank effects cannot permanently blind, deafen or sever Heimdall from his guardianship of Bifröst.
Legendary Resistance (5/Day). If Heimdall fails a saving throw, he can choose to succeed instead.
Magic Resistance. Heimdall has Advantage on saving throws against spells and magical effects.
Watcher of the Gods. Heimdall cannot be surprised. Invisible creatures, illusions and shapechangers within 1 mile do not gain Advantage against him merely from being unseen or disguised. He knows when a creature within that range teleports, changes plane or crosses a magical threshold.
Hears the Grass Grow. Within 10 miles, Heimdall can isolate a sound no quieter than normal breathing if he knows what he is listening for. Stone, weather and ordinary magical silence do not block this sense; an artifact, divine effect or specifically warded sanctum can.
Guard the Threshold. Hostile teleportation and planar travel that begins or ends within 120 feet of Heimdall requires the creature to succeed on a DC 36 Charisma saving throw. On a failure the movement fails, the action and spell slot are spent, and the creature takes 36 (8d8) Radiant damage.
Divine Immortality. Reducing Heimdall to 0 Hit Points defeats his present body but does not permanently destroy him without a valid divine-death condition. His foretold mutual death with Loki can satisfy such a condition.
Divine Spellcasting
Heimdall casts spells using Wisdom (spell save DC 36, +28 to hit with spell attacks). He requires no Material components.
At Will: any Cleric or Heimdall-granted spell of 5th level or lower.
3/Day Each: any Cleric or Heimdall-granted spell of 6th–8th level.
1/Day Each: any Cleric or Heimdall-granted spell of 9th level.
Actions
Multiattack. Heimdall makes three Hǫfuð attacks.
Hǫfuð. Melee Attack Roll: +23 to hit, reach 10 ft., one target. Hit: 37 (4d12 + 11) Slashing damage plus 45 (10d8) Radiant damage. Against a creature that teleported, changed shape or emerged from invisibility since the end of Heimdall’s last turn, the attack deals an extra 27 (6d8) Force damage.
Gjallarhorn — Warning Blast (Recharge 5–6). Heimdall sounds the horn. Every ally of his choice within 1 mile immediately ends Charmed, Frightened and unconscious sleep, may stand from Prone without spending movement, and gains 30 Temporary Hit Points. Every hostile creature within 300 feet makes a DC 36 Constitution saving throw, taking 88 (16d10) Thunder damage on a failure or half as much on a success. A creature that fails is Deafened and cannot become Invisible until the end of its next turn.
Open Bifröst (3/Day). Heimdall creates a rainbow bridge between two points he can perceive on the same plane within 1 mile, or between Himinbjörg and a known location on another world linked to Yggdrasill. The bridge lasts 1 minute. Heimdall decides which creatures may use it; hostile creatures attempting to force passage make a DC 36 Charisma saving throw or are cast back to their starting side and take 55 (10d10) Radiant damage.
Bonus Action
Gulltoppr. Heimdall calls Gulltoppr to an unoccupied space within 30 feet or dismisses him. While mounted, Heimdall’s Speed becomes 120 feet, and he can move across Bifröst, water and open air as though they were solid ground.
Reaction
I Saw You Coming. When a creature Heimdall can perceive within 120 feet makes an attack, teleports or moves through a doorway, gate or other threshold, Heimdall moves up to 60 feet without provoking Opportunity Attacks. If he ends this movement within reach, he makes one Hǫfuð attack against that creature. If the trigger was teleportation or planar travel, the attack resolves before the movement completes.
Legendary Actions — 4 Uses
- Watchman’s Step. Heimdall moves up to half his Speed.
- Hǫfuð. Heimdall makes one Hǫfuð attack.
- Expose the Hidden (Costs 2 Uses). Until the end of Heimdall’s next turn, Invisible creatures and illusions within 120 feet are outlined in golden light and cannot benefit from being unseen.
- Seal the Road (Costs 2 Uses). One doorway, portal, teleportation circle or 20-foot-wide passage within 120 feet becomes impassable to hostile creatures until the end of Heimdall’s next turn.
- Sound Across the Worlds (Costs 3 Uses). Heimdall makes a lesser blast of Gjallarhorn. Allies within 120 feet may immediately move up to half their Speed; enemies there take 33 (6d10) Thunder damage.
Divine Realm Actions — Himinbjörg
- Every Road Is Visible. Until initiative count 20 on the next round, Heimdall knows the exact location of every creature in Himinbjörg and on the nearby span of Bifröst.
- Rainbow Rampart. A 100-foot-long, 20-foot-high wall of prismatic light appears. Allies can pass through; enemies take 45 (10d8) Radiant damage when they first cross it.
- Alarm of Heaven. Up to six allies anywhere in Asgard hear Heimdall’s warning and may use their Reaction to teleport to unoccupied spaces within 60 feet of him.
Gjallarhorn — 5.5e
Wondrous Item, Artifact; normally entrusted to Heimdall.
- World-Voice. When Heimdall sounds the horn, its call can be heard across the worlds linked by Yggdrasill.
- Wake the Host. The bearer can cast divine word once per Long Rest and sending at will; Heimdall ignores those limits.
- No Secret Crossing. While attuned, the bearer knows whenever a portal opens within 1 mile.
- Ragnarök Call. The full prophetic blast cannot be reproduced casually. Sounding it as the true call to Ragnarök is a campaign-level event, not an ordinary item activation.

Divine Abilities
Perfect Watch (Ex). Heimdall cannot be surprised or flanked and automatically notices invisible or ethereal creatures within 1,500 feet unless their concealment is artifact- or deity-level.
World-Hearing (Su). Heimdall can make Perception checks based on sound across 10 miles without distance penalties. Magical silence created by a non-mythic source does not block this sense.
Threshold Denial (Su). Teleportation or planar travel within 120 feet requires a caster-level check against DC 38. Failure wastes the effect and deals 8d8 sacred damage to the traveller.
Gjallarhorn (Su). Once every 1d4 rounds Heimdall can sound a battle blast. Allies within 1 mile gain a +6 morale bonus on saves and attack rolls for 1 round; enemies within 300 feet take 16d6 sonic damage, Fortitude DC 48 half.
Divine Immortality (Ex). Defeating Heimdall’s present body does not permanently destroy him without a divine-death condition.

Gjallarhorn — Legacy Rules
When Heimdall sounds Gjallarhorn, every Æsir and Vanir hears it regardless of location. Other living creatures may hear it across the worlds, with easier Listen checks in Asgard than more distant realms. Mortals standing within one mile risk being stunned or permanently deafened by the blast. A bearer other than Heimdall must overcome extremely difficult Perform and Use Magic Device checks to sound it correctly.
Other Divine Powers
Heimdall can see and hear at supernatural distances, perceive attempts to reach Asgard as they begin, and perform Listen, Search and Spot checks as automatic divine actions. His senses and portfolio awareness are central divine abilities rather than incidental skill bonuses.

Campaign Present
What Is Heimdall Doing Now?
Heimdall remains at Himinbjörg, but his watch no longer means staring only at the visible span of Bifröst. Smugglers, giants, fey powers and planar predators increasingly use side-roads through Yggdrasill, hidden crossings and mortal ritual sites to approach Asgard without touching the bridge. Heimdall has expanded his watch to the pattern of crossings themselves.
He is especially alert to disturbances around Loki’s prison, movements linked to Fenrir and Jörmungandr, and any attempt to imitate the true summons of Gjallarhorn. A false horn-call is not merely sacrilege: it could move armies, trigger prophecies or cause gods to abandon positions they are meant to hold.
In Midgard, Heimdall’s agents favour watchtowers, ports, mountain passes, frontier roads and communities close to supernatural crossings. Their work is preventive. A threat stopped before anyone else notices is considered a greater success than a heroic defence after the walls are already burning.
The Watchman at Heaven’s Edge
Heimdall’s senses are among the most concrete divine powers described in the old mythology. He needs less sleep than a bird. He sees a hundred leagues by night or day. He hears grass growing and wool growing on sheep. These are not metaphors that need to be reduced to ordinary Perception proficiency: his role as guardian depends on truly superhuman awareness.
Himinbjörg stands beside Bifröst, where the guardian can watch the road into Asgard. His horse Gulltoppr belongs to the same golden imagery as his name Gullintanni, “Gold-Tooth.” Gjallarhorn is the final alarm: its blast reaches all worlds when the doom of the gods begins.
Hǫfuð, “Head,” is Heimdall’s sword. The surviving prose preserves a strange lost myth in which sword and head are poetically linked to him, a reminder that much of Heimdall’s mythology survives only in fragments.
Son of Nine Mothers
Heimdall names himself the son of nine sisters. Other surviving material repeatedly calls him the son of nine mothers, while later prose also calls him a son of Odin. The ninefold birth marks Heimdall as unusual even among gods.
In the campaign present the nine mothers are treated as a real divine lineage connected to the great sea-powers. Their shared motherhood explains Heimdall’s affinity with boundaries: sea and shore, world and world, waking and sleep, god and mortal. Priests often invoke all nine before beginning a watch whose failure could open a supernatural road.
Ríg and the Children of Heimdall
Ríg is one of Heimdall’s old walking-names in Midgard. Under that name he moves through households rather than fortresses, observing how people live, work, inherit and rule. The tradition links him with the ancestry of thralls, free farmers and rulers, making his guardianship social as well as military.
This aspect of Heimdall is particularly important to kings, judges and communities arguing about duty. Ríg does not teach that rank automatically makes a person worthy. He teaches that every station creates obligations, and that a society whose watchers, workers or rulers abandon those obligations has already opened a gate to disaster.
Living Worship
Heimdall is honoured by guards, watchmen, scouts, messengers, harbour wardens, gatekeepers, frontier communities and people responsible for keeping others safe while they sleep. His priests often serve where religion and public defence overlap.
Offerings
Polished horn, watch-bells, lamp oil, the first drink after a completed night watch, maps of dangerous roads and written reports of threats discovered before they struck.
Signs of Favour
A distant horn sounds once with no visible source, a guard wakes moments before an attack, frost outlines an otherwise hidden footprint, or a rainbow appears where no rain has fallen.
Signs of Warning
A watch-bell gives no sound, dogs stare at an empty gate, a familiar road seems one step longer than it should, or every sentinel in a tower dreams the same doorway.
Priestly Duty
Keep watch soberly, report danger without exaggeration, distinguish traveller from intruder, maintain roads and warning systems, and never manufacture fear merely to make one’s guardianship seem important.
Heimdall and Loki
Heimdall and Loki are mythic opposites without being simple mirror images. Heimdall identifies, guards and warns; Loki disguises, crosses boundaries and makes categories unstable. A lost story remembered in Skáldskaparmál even has the two contend for Freyja’s Brísingamen while transformed into seals.
Their final mutual killing at Ragnarök therefore grows from an older rivalry. Heimdall’s greatest strength is seeing what comes. Loki’s greatest strength is becoming what was not expected. Neither completely defeats the other’s principle before the end.
Adventure Pressure
The Horn Before Its Time
Gjallarhorn is heard once across Midgard, but Heimdall has not sounded it. Every divine power now wants to know who has reproduced the impossible call and what responded.
The Blind Mile
A one-mile section of Bifröst disappears from Heimdall’s sight while remaining physically intact. Travellers crossing it arrive with one memory missing.
Gulltoppr Returns Riderless
The golden-maned horse arrives in Midgard without Heimdall and refuses every attempt to lead it back toward Asgard.
The Tenth Mother
A sea-power produces an ancient oath claiming to be Heimdall’s tenth mother. The claim is false—but the oath itself bears Heimdall’s divine signature.
Deep Link Dive
Sources & Licensing
Gylfaginning gives the clearest description of Heimdall’s nine mothers, Himinbjörg, Gulltoppr, extraordinary senses and Gjallarhorn. Skáldskaparmál preserves his titles, the association of his sword with “Head,” and the lost story in which he and Loki contend for Brísingamen. The identification of Ríg with Heimdall comes from a late prose note attached to Rígsþula; the campaign accepts the identification as true even though its historical attribution is debated.
