Luminata is an Imperial Shrine World, that was visited by the Blood Angels' Primarch, Sanguinius, in the distant past. While there, he gifted Luminata's population with a Blood Chalice as a show of faith, which legends state was created by his own hands. A shrine, named Sanguis Gloria, was later built to contain the chalice and was always protected by ten Blood Angels. It was built atop a large mountain, known as the Crown, which was carved in the image of an angel, with wings. The angel was so vast, that it wore a cloud layer like a crown, which it was named after, and thousands of pilgrims always sang endless hymns in the shadows cast by its wings.
Despite this, there were those among the Blood Angels, who would have taken the chalice from Luminata if they could have. They explained that such a relic, should be cared for in the Chapter's Fortress Monastery, rather than be trusted with weak mortal hearts. Though their requests were denied, Luminata was later invaded by the Word Bearers Dark Apostle Tur Zalak, who sought to gain control of the chalice. He had hoped to use it in a plot to destroy the Blood Angels Chapter, but Zalak was defeated by Captain Larracus Donato's First Company, before he could do so. Luminata was devastated in the invasion however and Sanguis Gloria was left in ruins, after being set aflame by Zalak's forces.
