During the Clone Wars, the Jedi hunter Ochi of Bestoon hunted Jedi Master Depa Billaba on the Expansion Region planet Malathon IX. Ochi, who had taken a bounty for the head of Billaba, tracked her for five days before he eventually decided to spring his ambush on the fifth day. Before Ochi could take out Billaba, however, Mace Windu, Billaba's Master, who himself had been tracking the Jedi hunter, confronted Ochi and prepared to strike him down with his lightsaber.
