Temple of the Sun

The rulers of Mictlan gathered at the Temple of the Sun, located in the middle of Heart Lake, to hold council or sue for peace. It was a sacred space overseen by the Fallen One, the last of the Sky People, who had once lived in the splendor of the Sun before its death and the creation of the White Abyss; he had raised the Divine Children, including Ketzelkan, to inherit the Sun Realm, though he was sealed within the temple and forbidden from leaving.^[2]

• Cassie mentioned in Chapter 2772 that the Sun Temple was the Vanishing Lake Citadel which Nephis mostly destroyed in Chapter 1962 during her battle against Moonveil.
