The Shamus was a Nebulon-B2 frigate that served under the command of Imperial Grand Admiral Demetrius Zaarin. The warship was pivotal to the outcome of the battles in the Mylok system that centered around the transfer to Imperial hands of advanced hyperdrive technology developed by the Habeen and Nharwaak.

Future Emperor's Hand Maarek Stele was posted aboard the Shamus, and played a key role in the success of the frigate's engagements.
