The Githyanki are considered to be the most powerful and power hunger clan of the Gith. For reasons yet unknown, the Githyanki broke away from their servitude to Nool in the Between. The other Gith clans fought against the Githyanki, but they proved to be much more powerful than expected.
The Githyanki, in their relentless pursuit of dominance, have either annihilated or subjugated all other clans, save for the valiant Githinthor who continue to resist their rule.
The current leader of the Githyanki is General Dekomath Zedru.
It is believed that the Githyanki are involved in some sort of alliance with the Dooms, but the extent of the alliance is not fully understood.
