The dwarf that later became known as Old Slaughterbone was little more than a sociopathic killer on his home plane before being drawn to the Delve. Within moments of his arrival he had already started a homicidal rampage, taking to the inky alleyways of the Spire Cavern and eviscerating any he came across. Such rampant murder quickly drew the attention of Duruvoln, The Executioner and his sadistic servants. Intrigued at being able to gain further power from the depraved deeds he already took part in; the dwarf quickly became an exalted member within the bloody faith. After many years of ‘servitude’ to the Bloody God, he began to chafe under the semblance of a collar that he had under the more prominent members of the ‘faith’ and disappeared into the twisting darkness of the underworld surrounding the great city of the Spire Cavern. Through some sort of horrid ritual that none have lived to bare witness to, the depraved dwarf swore undying allegiance to solely Duruvoln himself and none of his other servants; in the process severing the very flesh from his bones in sacrifice to the bloody God. Sharpening the bones of his hands into razor needles, the blood red skeleton perpetually dripping gore became known as Old Slaughterbone, and his reputation as one of the most degenerate of the Murderous God’s servants has created quite the legend. Seemingly in direct contact with his God, the abomination stalks and tears apart any creature he is asked to, and in times of boredom, anyone he feels like. Neighborhoods that suspect that Old Slaughterbone is near often become desolate wastelands, either though a mass exodus or unparalleled carnage. Some say the very hint of his presence causes the weak willed to become murderous.
The undead dwarf is a terror to behold despite standing a mere four feet tall. Old Slaughterbone is a squat, broadly boned skeleton adorned solely in ever dripping red gore and fleshy bits. The bones of his hands have been twisted into savagely sharp claws and his skull is malformed into a perpetual grin of razor fanged teeth. No apparent intelligence dwells within his eye sockets, but the aura of menace and sheer terror is unmistakable. Some enterprising individuals have gone so far to take a regular animated skeleton and cover it in blood and unleash it into an area they wish to terrorize, sometimes to drive them out or to cause them to seek out help; help that they are all too eager to provide. Fittingly enough, some of these tricksters run afoul the true Old Slaughterbone and have helped to perpetuate the legend.
Malphas and Duruvoln are vying for control over Slaughterbone as the terror and bloody murder he spreads falls between their realms of power. Both greatly desire to keep him as a servant for the sheer divine power he is able to channel, even as a horrific corpse creature. Both send spirits and servants hoping to sway him into performing actions for them towards their ends, but more often than not all that achieves is a higher body count. Some have worried that the sheer savagery and legendary sorties that surround Slaughterbone independent of the Gods may grant him divine power of his own. A number of the fearful in the Spire Cavern have even set up mock shrines to ward away his attention, though such offerings never sway his coming.
