Sacopo was a blustery and boisterous character who, who Iaalu thought would have easily made Third Engineer were it not for his petty disagreements with Tenzaal. He was older than Iaalu by nearly a century.
En route to a battle, the Koramund was ambushed by zerg fliers and crashed into the planet Vanass. Sacopo and the other engineers survived in the hanger bay, but were killed by Tenzaal, who had plotted to destroy Koramund. Iaalu would discover his corpse after the crash, dangling from one of the control podiums with his nerve cords severed, and recognize his wounds as those from a psi-blade.
