The Arbiter is a protoss warship specializing in providing psychic support.

Overview
Arbiters were crewed exclusively by Judicators, unlike other warships that were manned predominantly by Templar. The Judicator used the Arbiter as a base to provide support using space-time manipulation.

The Judicator could generate a large reality-warping field that served to conceal nearby friendly units. The Arbiter had to remain firmly anchored in space-time to generate the field and so was not concealed. Arbiters could weaken space-time, tearing rifts in the fabric of space-time, creating a vortex linking another location to the Arbiter's location. This could be used to move personnel and supplies over long distances. On the other hand Arbiters could also strengthen space-time and create discrete pockets of space-time, trapping objects and preventing those objects from interacting with objects outside of their pockets.

Despite troop transport usually being left to shuttles, Arbiters were capable of transporting forces within their holds, including dragoons.

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

StarCraft
The Arbiter is a high cost support unit. It relies on fairly high shield and hit point strength to survive, rather than its low powered direct attack.

It has a passive cloaking field that cloaks all nearby friendly units, but not itself. A popular strategy is to attach Arbiters and observers to a carrier group. The carriers attack from under the cloak, and ward off attacks on the uncloaked Arbiters.

The Recall ability offers a powerful means of strategic movement. Arbiters may use Recall to teleport forces into an enemy base, circumventing any defenses.

Trivia
An arbiter (or arbitrator) is an individual whose decision the parties to a dispute agree to be bound in arbitration. This could be said to be representative of the Judicator Caste.
