Serenity

The Serenity was a Protoss Arbiter, captained by Judicator Assmael. Its combat record is unknown but was almost certainly deployed against the Zerg and perhaps against Tassadar's forces and the Dark Templar. Its ultimate fate is equally ambiguous, but as the Arbiters were lost when the Protoss abandoned Aiur, it may have been among them or later phased out.
