The official GemStone IV encyclopedia.
The arch wight moves along ponderously, its gaunt humanoid frame often bent nearly double as it walks through the corridors of the deceased. Massive upper arms contrast with a thin torso and narrow hips. Its liquid golden eyes seem to be filled with tiny red sparks, and the lack of flesh on its face causes the arch wight to sport a horrific toothy grin. Very proficient in the ways of magic, the arch wight feasts upon the flesh of the deceased, but often cooks the living to death before indulging in its grisly meal.
Arch wights cast Earthen Fury (917) which makes them relatively dangerous for their level.
Behind the Scenes
Wight lords were originally creatures of Castle Claedesbrim before replacing shadow assassins in the purgatory and frozen pit sections of The Graveyard. In their Rolemaster lore they are non-corporeal vestiges of nobility, found in burial mounds and the cemeteries of strongholds. Their description in the game itself was made to highlight the cannibalism theme in The Graveyard, represented also by the ghouls, which is also its relevance to their presence in Castle Anwyn. Castle Anwyn notably seems partly derived from Lovecraft's "The Rats in the Walls" where this happens deep below ground, where Nyarlathotep is at the center of the Earth like Satan, and victims had dug their way up from underneath.
