In the Dungeons & Dragons game, ethergaunts are ancient aberrations that once inhabited the Material Plane, but nearly ten millenia ago abandoned it for the Ethereal Plane. They view the current inhabitants of the Material Plane as vermin infesting their ancient homeworld, and seek to exterminate them. Ethergaunts look like extremely emaciated humanoids standing nearly 8 feet tall. They hide their alien faces behind masks, while tendrils hang from their head like long hair. Ethergaunts refer to themselves as "khen-zai". Their society serves consists of a rigid caste system.
