Months earlier, the USS Sarek began an excavation of an abandoned Romulan outpost at Ullho in the Typhon Expanse.  As quickly as their research started, the crew was re-assigned to the Delta Quadrant with the rest of Bravo Fleet for the blood dilithium campaign.  Upon the Sarek’s return to the Beta Quadrant, Science Officer Yuulik fabricated sensor readings to fool the Sarek crew into investigating a dangerous spatial anomaly she had faced once before in the earliest days of her career.

When the USS Olympic, of Sarek Squadron, was assigned to continue the excavation on Ullho, the ship was attacked without warning or mercy.
