Being a pacifistic race, the Ottiumigons had installed a minefield to surround their system, to discourage anyone from invading. This had little effect on the Yuuzhan Vong. Their leader, Hooley Krekk, had used his slaveships, to devour the mines and began to capture the Ottiumigons.
After the Battle of the Ottiumigos Centrality, renegade Jedi Knight, Nathaniel Kenobi, Kaminoan Prime Minister, Lama Su, and clones, Alpha, Doc, Sneaky, Crash, and Flyboy were sent on a recon mission. They were to investigate the Yuuzhan Vong occupation force.
Lama was captured in orbit by a slaveship, after his Stealth-Arc's cloak malfunctioned. He was then brought before Hooley Krekk and put in the Embrace of Pain. After an interrogation, he also received a slaveseed.
Nathan and the clones managed to make several "distractions" outside of his holding cell and Nathan charged in, lightsabers blazing, to rescue him. But Lama had drawn his last and after a battle with Hooley Krekk, Nathan forced the Yuuzhan Vong to surrender.
At the time of the Schism, Ottiumigos Prime was rumored to be a secret base of the breakaway Dark Jedi.
