Grey

Greys, also known as doppelgangers, changelings and fleshgaits are hairless, black eyed and grey-skinned humanoids. These creatures are from a previous world that was annihilated by Oblivion. They aligned themselves with perfection and secured passage into the next world. They are thought to dwell in the Outer Darkness, building cyclopean cities upon the surface of the Moon. They send agents to the world below to learn how to best bring down other civilisations.
To do this diabolical study of other species, they shape-change into other forms and walk amongst the native peoples of the world. Inexperienced greys often practise shape-changing for cycles before perfecting their art of mimicry. The face is the most difficult feature to copy convincingly.
Greys exist in all parts of the world, but their main base of operations is located in the high mountains that lie beyond the Dark Forest of Noz-Oraln. Keen scientists, the greys often abduct members of other species that stray into the haunted pine forests beyond civilisation. Such creatures are sometimes returned to their homes through unexplained means, sometimes apparently unharmed but occasionally displaying various incisions as those made by an adept barber surgeon. Some others even sport full amputations. Most cannot remember the details of their kidnapping, but a rare few babble horribly about bright, horrendous moonlight, flashing blades and impossible technology directed by cold, hate-filled eyes. They are usually dismissed as mindlessly insane victims of kiasyd cruelty.
Most greys worship Oblivion, although abductors frequently revere Amarok also, and veneration of the dragon Zoor'Ztsh is not uncommon. No species is as hate-filled as the greys, who were promised perfection only to have a new imperfect world emerge from the eternal Void in annihilation's wake. They do not intend for this to occur again.
Reproduction is a painful and unpleasant ordeal that this species engages in only to manage the build up of eggs within their bodies. Laying, or rather implanting, requires the insertion of millions of egg pods into living flesh, which upon hatching the tiny, maggot-like larval greys consume horrifically. It is thought that over one third of abducted victims are used as breeding incubators for young greys.
