Previously known as the Dedication, at some point Chur'R-Zhal and her crew took over the ship and renamed it the Rampant Perdition. During the ship's takeover the slipspace engines were locked down, preventing the Kig-yar from using them. Due to the Kig-yar's negligence the ship fell into disrepair. During this time a few Sangheili, Jiralhanae, and Marines were killed and pinned to a wall in the ship. In 2558 they captured another Sangheili who had been seriously injured in an encounter with a Guardian. Some time later they captured a human prison ship occupied by Commander Maya Sankar, Black-Box, Mshak Moradi, and Bostwick.
