Hellkyres are Hel's special servants. They normally look like hideous and twisted Valkyries. They are skinny and gaunt creatures, yet they are stronger than any mortal man. They ride Nightmares or other hideous creatures.
Unlike the Valkyries, Hellkyres do not mainly search for souls to serve their Queen. Hellkyres perform special tasks for their mistress only and are thus rarely seen outside Helheim, Hel's Homeplane. These creatures will attack Valkyries on sight, though few such battles have been reported. This may be due to the fact that very few Hellkyres exist.
Special abilities: Hellkyres are exalted creatures who can be killed. Like Immortals they can spend TP to gain the abilities of 36th level spellcasters. They do not need to eat sleep or breathe. They are Immune to energy Drain, disease, ageing and Immortal-level ESP spells. They only have one form and can not have a mortal identity. It takes a weapon +3 or greater to harm them. Hellkyres have Anti-Magic, but are affected by moral magic.
Characteristics: Ability scores are 1d8+25, except charisma which is 1d12+2
Note: This is not a mythological creature. More about Hellkyres can be found in The Primal Order.
Where found: Helheim, or elsewhere.
