Xel'Naga
The xel'naga were a god-like race from the Void who seeded life across the universe and sought to perpetuate themselves through the Infinite Cycle. They created both the protoss and the zerg, and the rogue xel'naga Amon's bid to end the cycle drove the central conflicts of the Koprulu Sector.

Daelaam
The Daelaam was the unified protoss government that bound the Khalai, Nerazim, Purifiers, and some Tal'darim together after the fall of Aiur, led by Hierarch Artanis through the End War against Amon and the reclamation of their homeworld.

Karass
Karass was a protoss high templar and praetor of the Daelaam whose mastery of psionic powers was considered legendary. On the eve of the Second Great War he led a force to Ulaan and sacrificed himself and his troops to cover the escape of Dark Prelate Zeratul.

Queen
The queen is a Zerg support strain derived from the Arachnis brood-keeper, bred to administrate hive clusters, oversee maturing broods, and serve as an infestation specialist. Two distinct forms exist across the history of the Swarm, the flying Great War queen and the ground-bound hive-master engineered after the Brood War.

Sarah Kerrigan, the Queen of Blades
Sarah Kerrigan was a psychic terran who began as a Confederate ghost, rose to be second-in-command of the Sons of Korhal, and after Arcturus Mengsk abandoned her on Tarsonis was captured and infested by the Zerg Swarm to become the Queen of Blades.

Zeratul
Zeratul was a revered Nerazim mystic and dark prelate who allied with Tassadar against the zerg, slew the cerebrate Zasz, and was manipulated by Kerrigan into killing Raszagal. His decades-long pursuit of the xel'naga prophecy shaped the fate of the protoss, and he gave his life freeing Artanis from Amon.
