The Xava'kai, the "Hands of the Benefactor", are a subgroup of the Tal'darim, a group of protoss stranded on Aiur following the closure of the warp gate. They began to lose their connection to the Khala due to their grief at being abandoned by their brethren and due to their addiction to the drug, Sundrop. They exiled themselves from the other faction of survivors, the Shel'na Kryhas. They were the most loyal to their mysterious leader, the Xava'tor.
