From Ardrana

Githzerai are the monastic, chaotic neutral counterparts to the githyanki. The two races share a stretch of time in history; the githzerai are the lesser and more repressed offshoot of the original people that the warrior Gith helped to escape the slavery of the mind flayers millennia ago.

Githzerai are very similar in appearance to their githyanki cousins, although they tend to look much more human. Their features are for the most part unremarkable, with vaguely noble countenance. Their skin tone is that of human caucasian flesh. Githzerai dress simply, wearing functional clothing and favoring conservative tones.

Githzerai have taken what some might call an inordinate interest in Ardrana, perhaps because of the githyanki's interest in acquiring powerful artifacts from the world. On the other hand, perhaps it's the other way around. In any case, the githzerai have established a secret fortress somewhere on Ardrana from which they occasionally send individuals on missions.

Githzerai have a very specific naming fashion. While their first and last names are similar to human construction, their middle names denote their home. Those who have left the plane of Limbo must take the middle name of "es'Trehoth".

Note: Githzerai originally appeared in this form in the 2nd Edition Monstrous Manual for the AD&D game from TSR. Their use here is for the purposes of providing context for the campaign only.
