In 2553, in an effort to strengthen the emerging alliance formed between the Unified Earth Government and the nascent Swords of Sanghelios, the Makar-pattern light corvette The Lookout was deployed—with crew from both the Swords of Sanghelios and the UEG's United Nations Space Command, including Slight List—on a mission to reestablish contact with human colonies cut off during the Human-Covenant War.
After months of searching, The Lookout came upon the system where the colony Losing Hand was located. Initially thinking the system to be barren, it was upon Slight List's insistence that the system was surveyed. After discovering Losing Hand, the ship landed and Slight List almost immediately turned its attention to the crashed ship, UNSC Dark Was the Night. After establishing contact with the ship's surviving crew and locals, The Lookout extracted any humans on the planet that sought to leave. For those that desired to remain, Slight List and other crew members of The Lookout spent two weeks turning Dark Was the Night into Losing Hand's primary power station. Afterwards, Slight List and the rest of The Lookout's crew departed the planet to continue their mission.
