Vlaakith

In the Dungeons & Dragons role-playing game, Vlaakith is the name of the first ruler of the githyanki race after the death of Gith, the rebel leader that united them against the illithids.

History
Vlaakith I was an advisor to Gith and helped seal the pact between red dragons and the githyanki. All subsequent queens of the githyanki have been named after her. The last queen of the githyanki, Vlaakith CLVII, died after ascending the throne without giving birth to an heir, but returned as a lich, a type of undead. Vlaakith has ruled the githyanki for over a thousand years. Her home, the Castle Susurrus, is in the githyanki capital city, Tu'narath, which is built on the god-isle of a deceased power known only as "The One in the Void".

The Lich-Queen's Beloved
In an adventure entitled "The Lich-Queen's Beloved" in Dungeon issue 100, she was presented as a direct adversary who could be defeated and slain by adventurers. The adventure also revealed that she had been siphoning off the power of a dead god (now resembling rock) on which Tu'narath was built, which she accomplished, rules-wise, by killing Githyanki that had risen above character level 16. This in turn gave her enough experience points to cast thousands of wish spells and come a fraction closer to getting the dead god's power and becoming a deity. The adventure takes place just as Vlaakith is about to ascend to godhood, and describes the consequences if the players allow her to succeed.
