Although the Khala has called upon the Protoss to forsake their ancient Tribal society and embrace the new castes of Judicator, Templar and Khalai, many still cling to the fleeting customs and trappings of the old ways. The various Tribes remain intact only to remind the Protoss of the follies of their past. With the ascension of the Judicator as the ruling caste above all Protoss, the old dilemma of Tribal separatism no longer threatens the greater society. The most distinguishable aspect of the Tribes is that each sect of Protoss has its own unique skin shades ranging from mottled grey to a dark, aphotic blue.

Ara

Caste : Judicator

Station : Conclave Praetor Guard

Tribal colour : Red

The Ara is a relatively young Tribe, by Protoss standards. They were the first group to rally behind the vision of Khas [...] for a unified race after the ending of the Aeon of Strife. The youthful enthusiasm of the Ara helped to promote the mandates of the Khala, and ease the fragmented Tribes into a lasting peace. The Ara maintains the power within the Judicator caste and thus controls who presides within the ruling Conclave. In light of recent events, the Ara hold to the tenet that the Zerg should be the greatest concern of the Protoss and that Humanity should be left to its own fate.

Akilae

Caste : Templar

Station : High Templar Command

Tribal colour : Green

The Akilae represent the strongest fighting force within Protoss society. The Akilae dominated the other Tribes for hundreds of years during the Aeon of Strife [...], but quickly saw that Khas´ vision of unity heralded a bold new age for their race. Entrusted with protecting the Homeworld of Aiur [...], the Akilae have stalwartly upheld their charge for generations. Led by the powerful High Templar [...], the Akilae command the might of all Protoss Templar at war. Although extremely loyal, the Akilae have recently argued with their Judicator superiors that Humanity should be saved from the Zerg threat, not arbitrarily destroyed because of it.

Shelak

Caste : Judicator

Station : Librarians, Keepers of the Khaydarin Crystals [...]

Tribal colour : White

The Shelak Tribe was the Tribe closest to the ancient Xel´Naga race. Therefore, they were appointed by the Judicator to study and protect the powerful Khaydarin Crystals that empower the awesome technologies of the Protoss [...]. The Shelak, intrigued by the legacy of the Xel´Naga, continuously study their ancient texts. Although the Judicator have banned all Xel´Naga teachings, the Shelak are still allowed access to the archives. The Judicator hope that the Shelak can unravel the mysteries of the Xel´Naga and thus expand their knowledge through the Khala.

Sargas

Caste : Templar

Station : Enforcers/ Assassins

Tribal colour : Blue

Easily the most notorious of the Tribes, the Sargas have offered a tenuous allegiance to the Judicator Conclave. Much like the Venatir before them, the Sargas continually fight to override the effects of the Khala upon their Tribe. Obsessed with holding onto their free will and Tribal identity, the Sargas offer their aid only when it serves their purposes. The Conclave has found that the Sargas are extremely adept at the arts of killing. Thus, their members have been made the official assassins of the Protoss, deftly eradicating any dissidents or enemies with the ancient grace of their hunter-race. It has been noted that more Dark Templar stem from the Sargas Tribe than from any other.

Auriga

Caste : Templar

Station : Protectors of the Great Fleet

Tribal colour : Orange

Charged with servicing and operating the massive Carrier [...] ships and Arbiters [...] that protect the space-ways of Aiur, the Auriga Tribe has never faltered in its duty to the Conclave. Tens of thousands of years ago, they were the first to construct sailing ships that they boldly launched upon the furious seas of Aiur. Captivated with the thrill of driving their vessels into the unknown, the Auriga stand ever ready to combat any threat that might loom above the Protoss Homeworld.

Furinax

Caste : Khalai

Station : Weaponsmiths and Technologists

Tribal colour : Purple

Even though the Furinax Tribe reviles warfare of any kind, they can be counted upon to defend their Homeworld with savagery and honour. For generations the Furinax have served their race as weaponsmiths and builders. Obsessed with merging the sacred energies of the Khaydarin Crystals [...] with modern technologies, they revel in their progressive crafts. The greatest feats of the Furinax Smiths are the revolutionary power suits of the Zealots [...] and the powerful Dragoon [...] exoskeletons.
