Like all Vorta field supervisors, Keevan was the Dominion official in charge of a Jem'Hadar unit. In early 2374, Keevan and his unit of Jem'Hadar crashed on a class M planetoid within a dark matter nebula in Cardassian space. With his ship destroyed and only a handful of vials of ketracel-white remaining, Keevan was forced to ration it among the ten Jem'Hadar who survived. To make matters worse, Keevan himself received serious injuries in the collision and the unit's communications equipment was heavily damaged, leaving them unable to submit a distress call.
