The Sentinel fleet watches over galaxies and enforces law and order. They are robotic starships that fly around, and warp into battle to fight pirates, smugglers, and resource abusers. They are alerted by Wave alerts and Defense Chits (which tell them someone is under assault). They require obedience.

They have fast, and agile ships, but they are very fragile. They have a photon cannon, phase beam, and a deployable and rechargeable energy shield. They have limited sentience and can’t speak.
