During the time of the Clone Wars, Ochi of Bestoon, a Jedi hunter, was engaged in the pursuit of Jedi Master Depa Billaba on Malathon IX, a planet located in the Expansion Region. Having accepted a bounty for Billaba's capture, Ochi pursued her for a period of five days, finally choosing to execute his surprise attack on the last of those days. However, before Ochi could eliminate Billaba, Mace Windu, Billaba's own Master, who had been following the hunter's trail, appeared and readied himself to attack Ochi with his lightsaber.
