Arbiter

"Warp fields stabilized"

- Protoss Arbiter

The Arbiter-class starship is the only Protoss warship to be crewed exclusively by non-Templar. Instead, it is crewed by psychic Judicators The vessel serves as a point of focus to allow its psychic Judicator crew to cast a reality-warping field, rendering all friendly units within its field of influence invisible to enemy sight. However, all Arbiters within this field are immune to its effects because they are required to stay firmly grounded within space time in order to safely generate and project the field. This cloaking field is used automatically and does not deplete the starship of any energy at all.

After the Judicator Caste was eliminated from the Protoss power structure, the Arbiter quickly fell into disuse. When the Protoss fled to Shakuras, the Arbiters were lost along with Aiur.

Game Unit
The Arbiter, with its weak attack, should not be relied upon for combat and should instead be used for its special abilities.

The Arbiter doesn't feature in StarCraft II, having had its abilities taken at first by the Phase Prism and Star Relic; the Mothership's role later replacing that of the latter (taking its cloaking field ability).
