The Nostalgia for Infinity was originally an Ultra-owned lighthugger. Sometime centuries before the outbreak of the Melding Plague, the crew of the Nostalgia for Infinity managed to located -- and circumvent the security measures of -- a Conjoiner asteroid in a nameless brown dwarf system. The automated installation contained the intentionally forgotten cache weapons, which were appropriated by the Ultras. In 2651, Nostalgia for Infinity arrived in the p Eridani system, having fled both the Inhibitors and Skade's armada, and came to rest on a planet named Ararat.
