Bones of a New World (Su)

If Ymir is ever slain, both its rejuvenation and immortality qualities apply, but the massive elemental creature’s corpse falls to the ground as the seed of a new demi-plane, which can be shaped into a new nation, perhaps even a world. A new incarnation of the immortal Ymir rises from the icy bones of his former self, and departs for new battles.

The Ymir-corpse left behind acts as the seed of a massive, private demi-plane cast by a 55th-level caster and responds to the commands of the creature who struck the deathblow as if he or she were the creator. If allowed to grow for a year or more, this demiplane can expand to form a cold new nation of towering mountains, deep forests and wide, fresh rivers. This land is rich in natural resources and game.

If Ymir is slain in space, or if the demiplane is moved into deep space somehow, it instead produces an Earth-like world with 1d4-1 moons and rich natural resources. The world establishes a stable orbit around a nearby star, or becomes a rogue exo-planet with Earth-like conditions, including a short day and long, chill night sustained by ambient magic.

Glacial Strikes (Ex)

Ymir is such a massive being, when it attacks, it also applies the attack roll to all creatures in squares adjacent to its intended target. All creatures successfully struck by this attack suffer the same damage.

Hypothermic Insanity (Ex)

Any creature that attempts to interact directly with Ymir’s thoughts (such as via detect thoughts or telepathy) must succeed at a DC 43 Will save or be driven permanently insane. This duplicates either the effect of the insanity spell, or the insanity rules, in which case the save DC is also the ongoing insanity DC. Ymir does not activate this ability when using his telepathy to communicate, unless Ymir spends a standard action to focus his mind on one opponent. This is a mind-affecting effect.

Additionally, any creature driven insane by Ymir’s presence gains vulnerability to cold, and loses any resistance or immunity they would normally possess. This Vulnerability remains until the insanity is cured. Victims driven insane by Ymir’s presence are disturbingly obsessed with the weather, and often die of exposure if not actively prevented from committing suicide by exposure.

Ice Rime (Ex)

Any spellcaster who fails to penetrate Ymir’s spell resistance with any spell with the [fire] descriptor is punished by suffering 4d6 points of cold damage (Will DC 43 half).

Primeval (Su)

Ymir is a truly ancient, primordial being that predates the birth of the gods and the formation of the multiverse.

  • Ymir’s attacks overcome all forms of damage reduction.
  • Ymir gains maximum hp from all Hit Die.
  • In addition, Ymir is treated as a 10 Tier mythic creature for determining how mythic powers and abilities affect him.
  • Ymir can use a mythic surge (+1d12) up to 10 times per day.

Unspeakable Presence (Su)

Ymir’s mere presence inflicts horrible mental anguish and torment upon all creatures within 300 ft. who can clearly see and hear Ymir; despite the blizzard conditions around him, Ymir is always clearly visible through the storm. A creature affected by Ymir’s unspeakable presence immediately extinguishes all light sources and heat sources, and begins to strip off all clothing and armor. The nude victim falls to its knees and worships Ymir, screaming incoherently until it succumbs to hypothermia.

A successful DC 43 Will save negates this effect.

A creature who saves cannot be affected by Ymirs’ unspeakable presence for 24 hours; this is a mind-affecting effect.

Winter’s Heart (Su)

Ymir is accompanied by an eternal blizzard. Ymir is surrounded by an aura of intense, arctic cold that extends 500 ft. This area is treated as a blizzard, with high winds and sleet. Winds are considered to be windstorm strength.

An area several miles in diameter also experiences unseasonably intense cold and driving snowfall, though of less dramatic strength.

Ymir is never impeded by severe weather, and can see through sleet, snow and precipitation without penalty, no matter how severe.


Environment any
Organization solitary and unique in the multiverse, sometimes accompanied by vast tribes of frost giants and similar creatures of elemental cold
Treasure virtually incalculable, easily 3x-5x standard! (deposits of gold, diamond, silver and rare-earth elements in Ymir’s body or worlds carved from his flesh)

Ymir is one of the eldest beings in the multiverse, a titanic and primeval being of raw, elemental cold. Soaring on vast wings of gleaming ice, Ymir wanders aimlessly through the depths of space, a continent sized comet with the intellect of a god. Ymir has no agenda, seemingly no memory and only a dim, savage sentience, but occasionally the ice-lord will display a scholar’s intellect and lecture (in a booming voice) on the true origins of the multiverse. Ymir barely notices humanity or its cities, farms or settlements; even armies on the march barely merit interest. Only great heroes, demi-gods and mythic creatures earn even a passing glance from the imperious, spiritually detached Ymir. Convincing the taciturn Ymir to share what he knows about the history of reality itself is a truly epic task.

Ymir demolishes worlds at his whim, but occasionally a champion and powerful allies resists Ymir’s depredations and slays the ice-lord, however briefly. Such worlds are rewarded with verdant new wilderness. At other times, in other places, where the battle was fought between the stars, Ymir’s bones become the core of newborn, living worlds.

According to the Norse, Earth itself was once the site of one such epic conflict. Ymir does not begrudge the creation of new lands and worlds from his fallen selves, but might return aeons after a defeat to once again challenge the strength of those land’s inhabitants.

Ymir is a mountain of freezing ice wrapped in a swirling corona of blizzard conditions and arctic fury. The creature is massive beyond imaging and weighs millions upon millions of tons. Ymir’s immense wings gleam like glaciers in the sun.

Ymir has little interest in mortal skills, but the creature is very knowledgeable about the structure of the multiverse, its true history and the true nature of the upstart Gods themselves.
