The Chaos Gate is the source of Chaos and Corruption in ADOM, and closing the gate is the main objective of the game for the majority of PCs (all those not pursuing ultra endings or the ordinary chaos god ending). As the main objective of the game, closing the Chaos Gate is naturally an involved process that involves various locations in the game. Upon his death (or resurrection), Khelevaster will impart the details of the process necessary to close the Chaos Gate to the player: acquire the four Elemental Orbs hidden in temples within the Caverns of Chaos and the one located in the Tower of Eternal Flames, and bring the orbs to the lowest levels of the Caverns of Chaos.
