Terrorist attack on Sedra City

A terrorist attack on Sedra City was carried out by an unidentified Sangheili Zealot on February 7, 2556. Although an ONI team led by Lt. Commander Jameson Locke tracked and attempted to stop the Zealot, they were unable to prevent the attack. Locke's team and the Sedran Colonial Guard collaborated to stop the terrorists from obtaining more of the element used to create the bioweapon. They traced the origin of the element to a partly intact segment of Installation 04, which had attempted an emergency slipspace jump during its destruction years earlier.
