The ISA Cruiser New Sun is the flagship of Battle Group Mandrake, a task force consisting of ten divisions of ISA legionnaires, used during Operation Archangel. It was under command of Colonel Jan Templar. During the course of the invasion, the cruiser was docked over Pyrrhus and was eventually attacked by Helghast forces, which resulted in the execution of Templar and ISA scientist Evelyn Batton by Helghast Colonel Radec and his forces, who were searching for the code data for the nuclear weapon Red Dust.
