Endion
Protoss Research Moon
Endion was a forest moon orbiting Bellum IV that served the protoss as a secluded research retreat for millennia. During the End War it was infested by Amon's brood and ultimately scoured of all life by a purification beam fired from Cybros.
Endion was a forest moon orbiting Bellum IV, used by the protoss as a research retreat for millennia. It was here that the greatest protoss scientists secluded themselves from political affairs, and here that the psionic matrix was first conceived. During the End War, Endion became a battleground when Amon's brood descended on it to stop the Daelaam from reactivating the Purifiers stored at the nearby world of Cybros.

A research retreat#
Endion served as a research retreat for millennia. The greatest protoss scientists secluded themselves there, away from political affairs, to focus on devising technology that would benefit the Protoss Empire. The psionic matrix was first conceived on the moon. (StarCraft II: Legacy of the Void)
After the Purifier Rebellion, Endion was chosen as the world that Cybros was to orbit. The scientists of Endion constantly improved its stasis grid, which was sealed by complicated locking mechanisms that could only be destabilized by an artifact known as the Megalith. (StarCraft II: Legacy of the Void)
The End War#
During the End War, Amon's zerg brood descended on Endion and overran its population along with the contingent of Templar assigned to defend it, infesting the forests. Using colossi developed on Endion, the protoss secured the area around the Megalith and warped in a nexus point. Phase-smith Karax activated the Megalith, which the protoss escorted to the stasis locks. Once the grid was down, Hierarch Artanis had all forces recalled from Endion's surface. (StarCraft II: Legacy of the Void)
After a battle to purge the zerg and hybrid from Cybros, Executor Clolarion fired a purification beam from his station, purifying all life on Endion. All zerg presence on the surface was annihilated. (StarCraft II: Legacy of the Void)

Cybros
Cybros was the home warship and space platform of the Purifiers, a command vessel held in stasis above the moon Endion until Artanis reactivated its robotic warriors during the war against Amon.

Artanis
Artanis was the Hierarch of the Daelaam, a renowned warrior who rose from executor during the zerg invasion of Aiur to lead the reunited protoss. He forged the Khalai and Nerazim into one people, reclaimed Aiur, and led the alliance that banished Amon from the Khala.

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.

End War: Amon's crusade on the galaxy
The resurrected xel'naga Amon corrupted the Khala and cost the protoss both Aiur and Shakuras. Kerrigan, remade as a xel'naga, killed him in the Void.

Karax: the phase-smith who armed the Spear
A Khalai worker who rose to keep the arkship Spear of Adun flying and armed. Karax prepared the Keystone that finally drove Amon out of the Khala.

Protoss
The protoss are an ancient, psionically gifted humanoid species native to Aiur, uplifted by the xel'naga and bound together by the Khala. Among the three dominant species of the galaxy, they are the most technologically advanced, and the most divided by their own history.

Every Zerg Brood, From the Garm Brood to Kerrigan's Swarm
Every named zerg brood in StarCraft, from the Overmind's six great broods of the Great War to the broodmothers who served the Queen of Blades. Each entry covers who led it, what it was good at, where it fought and how it ended.
Glassing
Glassing, also called planet cracking or purification, was a protoss war technique used to destroy all life on a planetary surface, usually to eradicate the zerg. Carried out by ships firing massive energy beams, it could disperse a world's atmosphere and burn through its crust.
Khalai Caste
The Khalai Caste were the working class of the Protoss Empire, the artisans, scientists, and builders who formed the great majority of the protoss population. Long regarded as the lowest of the three castes, they were dissolved during the End War when the age of the caste system came to an end.
Psionic matrix
The psionic matrix, also called the psi-matrix, was a field of energy emanating from Aiur that powered protoss structures and units. Tapped through pylons and nexus links, it was first sparked in 500 B.C.E. and later dismantled to deny Amon the Golden Armada.
Purifiers: protoss minds inside machines
The Conclave built them from the recorded minds of the greatest protoss warriors, then enslaved them. Artanis woke them again to fight against Amon.
Rohana: the last grand preserver
Rohana was one of three grand preserver sisters who conceived the arkships during the golden age of the Protoss Empire and then buried herself in stasis aboard the Spear of Adun. Awakened by Hierarch Artanis after the corruption of the Khala, she refused to sever her nerve cords and became both Amon's mouthpiece and the only protoss able to read his mind.
Second Age
The Second Age was the era of protoss history that followed the founding of the Khala, when the warring tribes were reorganized into a unified caste society, rebuilt their homeworld of Aiur, and resumed the spacefaring expansion that carried their civilization across the stars.
Spear of Adun: the ark buried under Aiur
Built in the Golden Age to outlast a calamity, the arkship waited beneath Aiur for centuries. Artanis raised it when Amon seized the Golden Armada.
Talandar
Talandar was a protoss purifier built from a brain scan of the Templar hero Fenix. Awakened during the End War believing himself to be Fenix, he came to accept that he was a separate being and chose his own name, becoming a leader among the purifiers of the Daelaam.
