Uraj Crystal
the sacred khaydarin shard
The Uraj is a sacred protoss khaydarin crystal left behind on the world once called Khyrador. With its counterpart, the Khalis, it was used to activate the xel'naga temple on Shakuras during the Brood War.
The Uraj is a khaydarin crystal shard held sacred by the protoss. Its counterpart is the Khalis, the crystal tied to the Nerazim. Together the two crystals served as the keys that activated the xel'naga temple on Shakuras during the Brood War. (StarCraft: Brood War)
Origin and guardianship#
The games say little about where the Uraj came from. During the Brood War, Zeratul told Kerrigan that the world where it lay had long ago been a protoss colony called Khyrador, and that the planet and the crystal were abandoned when the strife between the protoss tribes escalated. (StarCraft: Brood War)
Blizzard's planetary profile of Braxis, as Khyrador later became, gives a different cause. It says the world was home to the Uraj during the golden age of protoss expansion and was abandoned when a series of violent psionic storms rocked the planet and drove the protoss settlers away. (Koprulu Sector Systems: Braxis)
The Brood War#
During the Brood War, the Uraj was recovered by Sarah Kerrigan together with a protoss army led by Praetor Artanis and Dark Prelate Zeratul. They overcame the Terran Dominion defenses guarding it and sent in a probe to gather the crystal. (StarCraft: Brood War)
The protoss returned with both crystals to Shakuras. Artanis carried the Uraj into the xel'naga temple and inserted it into the structure's mechanisms. The temple's activation created a giant energy burst that scoured the zerg from the planet. (StarCraft: Brood War)
The End War#
During the End War, as Artanis made preparations to overload the xel'naga temple of Shakuras, he lamented that the protoss no longer had access to the Uraj or Khalis crystals, the absence of which lengthened the temple's configuration procedures. (StarCraft II: Legacy of the Void)

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.

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.

Brood War: Kerrigan's war for the Swarm
The Brood War was a zerg civil war between Kerrigan and the cerebrate Daggoth over who would succeed the Overmind. The UED invaded from Earth at the same time.

Dark Templar (Nerazim)
The Nerazim, known to outsiders as the Dark Templar, are the protoss tribes who shunned the Khala, severed their nerve cords, and drew their power from the Void instead. Banished from Aiur, they became masters of shadow and exile before reuniting with their kin under the Daelaam.

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.
