Odionate was the name given by Jedi Master Vannar Treece to one of the "successor states" to the Chagras Hegemony established in a portion of the Grumani sector following the death of its titular ruler Chagras in 1040 BBY. It was named after its ruler, the Sith Lord Odion. Odion's followers were known as Odionites. Following the Battle of Vanahame, its titular ruler was killed and the state collapsed with its territories and assets being divided up among the Calimondra family.
