Harkaan worked as a poacher. In about 32 BBY, a meteorite crashed onto the moon Dorumaa and awoke a Dorumaan leviathan, a type of giant sea creature. Harkaan and some other poachers planned to kill the creature and then loot ivory from its corpse. However, the heroes of Cularin, a group of freelance agents who operated in the Cularin system, attempted to save the leviathan, by attacking the poachers. Harkaan and the poacher Pardo continued to attack the creature, while three other poachers tried to fight the heroes. However, the heroes eventually defeated the poachers and saved the leviathan.
