Githyanki

Dungeons & Dragons Githyanki
In the role-playing game Dungeons & Dragons, the githyanki, the Children of Gith, are a humanoid race living in the astral plane descended from the escaped thralls that overthrew the planes-spanning empire of the Illithids thousands of years ago under the leadership of a female rebel named Gith. The Githyanki have been ruled by the lich-queen Vlaakith CLVII (named for the adviser of Gith), a corrupt and paranoid undead wizard, for over a thousand years.

Dwelling in the timeless Astral Plane, the Githyanki inhabit numerous fortresses constructed from materials imported to the Astral Plane as well as cities built atop god-isles, the vast stone corpses of deceased gods. Their capital and largest city, Tu'narath, is built on the god-isle of a deceased power known only as "The One in the Void".

Bred from the beginning of their history to hate the illithids and any form of slavery or tyranny, githyanki are a race of warriors, excelling at swordplay and the creation of ornate armour and weapons.

Githyanki in Neverwinter Nights 2
An artifact of githyanki, the Sword of Gith, exploded across the planes during the great battle between King of Shadows and unknown sorceror, and a piece of it got stuck in NWN2's PC when he/she was a baby. And now githyanki want this piece back, no matter what.
