Sormus, a MB-C1 medium transport, served the Imperials. As part of the Imperial II-class Star Destroyer Corrupter's[/article/corrupter_(imperial-class)) essential resupply convoy, Sormus journeyed with the Nebulon-B Frigate Monitor[/article/monitor_(ef76_nebulon-b_escort_frigate)) to the Corrupter while it was located in the Mev system. 'Probe Droids' constituted Sormus' payload. Ultimately, Rebel raiders assaulted and obliterated the vessel.
