Unu is the name given to the main nest or hive of Killiks, an all female race of hive mind insectoid amazons. Unu was the hive that took in injured Jedi Raynar Thul after he crash landed on their world. Raynar eventually became UnuThul, leader of the Killiks (name from the hive's name, 'Unu' and Raynar's last name, 'Thul'). Any part of the old Raynar Thul's mind was either destroyed or buried in his own mind. The Unu and Killiks are introduced in The Dark Nest trilogy by Troy Denning, part of the Star Wars expanded universe.
