Aeon of Strife

During the Aeon of Strife, Protoss advancement slowed, and the tribes waged a massive war with each other, lasting hundreds of years. Little is known from this time, but it is known that the Protoss lost their psionic link with each other. The Aeon of Strife was the longest, most devastating civil war to ever strike any currently known species. The most famous Tribe from this time period is the Akilae Tribe, which are to this day renowned as the Protoss' finest psionic warriors.

During this time, the Protoss maintained colonies on other planets, but these too quickly became gripped with the Strife.
