History
The name first appears in Invisible Cities, in the looters’ side journey, as the final depth behind the shadows that corrode the cycle. The Cannibal Hymn, from the pyramids of Unas and Teti, is read as the true account of how Erebus and the shadows devoured the gods; hence Olympus is empty.
Some three hundred years later, around 1784 A.D.A., it returns as the weapon with which Auro, now Horseman of War and master of the Prism Keep, plans to end the cosmos after enthroning himself.
