The Ara's tribal color is red.
The Ara Tribe was one of the many protoss tribes that existed during the Aeon of Strife, though was considered to be a younger tribe. They were particularly antagonistic to the Shelak Tribe, and saw their clinging to the xel'naga that abandoned them as abhorrent. The two fought brutal battles across the surface of Aiur. However, following the Shelak mystic Khas uniting the protoss through the Khala, the Ara helped to promote the mandates of the Khala and to ease the fragmented tribes to a lasting peace.
Upon the creation of the caste system, the Ara came to control the Judicator Assembly, thus being the dominant force within the Conclave (most of whose members were members of the Ara Tribe). In addition, the Ara Tribe operated the khalen'ri (khalani for Conclave Praetor Guard).
Upon detection of the zerg threat within the Koprulu sector, the Ara argued that the aliens should be the greatest concern of the protoss, regardless of the fate of humanity. In this, their wish was granted, though Executor Tassadar came to defy the Conclave's will.
Months later, during the early stages of the zerg invasion of Aiur, the Ara Tribe made a last ditch attempt to defend the protoss temple from them, but failed. To make matters worse, the tribe had to deal with their fellow protoss, defending Kor-shakal from Tassadar and Dark Prelate Zeratul during the Protoss Civil War, but were defeated. However, Tassadar was captured during the battle and put on trial, also defended by the Ara Tribe, before his followers rescued him.
- Ara means "altar" in Latin. It is possibly a reference to the Ara tribe's religious dedication to the Khala. The insignia of the Ara tribe resembles a fire, which is sometimes used as a religious symbol. Ara is also the name of a constellation.
- According to the StarCraft manual, the Ara Tribe was formed from the first group of protoss to rally around Khas and his vision of protoss society, the Khala, at the close of the Aeon of Strife.
- In StarCraft: The Board Game, the Ara Tribe symbol is the symbol for the Aldaris faction.
