Forged in the biting frost of the Kirvaless peaks, the Kirvalassions are a grim and industrious people who blend the endurance of tundra nomads with the forbidden lore of diabolism. Known for their thick, braided beards and heavy fur mantles, they are the bulwark against the night, using siege tactics and blood-bound magic to protect their motherland from vampires and werewolves alike.

Kirvalassions are defined by a stocky, powerful build suited for heavy labor and mountain traversal. Their skin is typically ruddy or sun-scorched to a deep bronze, contrasting with thick, dark hair often worn in intricate braids. Most notable are their fiendish features: sharp, carnivorous teeth and eyes that glow with faint, amber, or violet infernal light. Their stomachs are remarkably hardy, and they possess claws suited for scraping through frozen earth.

Kirvalassion life is a cycle of nomadic wandering and sudden, intense fortification. They travel in great clans alongside massive war-mammoths and woolly sheep, moving between seasonal hunting grounds. Their culture is one of pragmatic grimness, where blood magic is seen as a necessary tool for survival. They value innovation, constantly refining their black-powder weapons and mechanical traps to stay one step ahead of the predators that haunt their borders.

Most Kirvalassions lean toward Lawful alignments, valuing the strict hierarchy and discipline required for siege warfare. Their religion is a transactional form of diabolism, where they make pacts with lower-planar entities to gain the strength needed to hunt even greater evils. They view their souls as currency to be spent wisely for the defense of the clan.

When a nomadic clan chooses to root, they build with astonishing speed. They construct 'Kremlins' or small fortified keeps that utilize local stone and timber, layered with alchemical sealants. Over generations, these forts expand into sprawling mountain cities, characterized by deep underground bunkers and massive walls designed to withstand years of siege.

Other races often view Kirvalassions with a mix of fear and respect. Their ties to fiends make them pariahs in more 'enlightened' kingdoms, yet their mastery of anti-vampiric warfare makes them indispensable mercenaries. They tend to be blunt and transactional in their dealings, preferring a honest bribe or a clear contract over social pleasantries.
