Akenathen Tandin was a male human who served as general of the Royal Onderon Militia during the Clone Wars. After a Separatist-backed coup allowed Sanjay Rash to replace Ramsis Dendup and the king, Tandin remained loyal to the throne. However, Tandin began to feel doubt about his loyalties after witnessing Rash deal with the growing rebellion. He later betrayed King Rash, with him and his forces fleeing with the rebels after they successfully rescued Dendup and rebel leader Saw Gerrera from execution.
