Throne of the Elements

In the Aeon of the Champion story series, the Throne of the Elements is the seat of power for the elemental spirits on planet Prarvis, located in a once highly-secret location since revealed to be Throne Hill in the northernmost, jungle-like region of the planet. It is actually hidden inside the hill, lying at the heart of a network of passages leading to different structures within the natural mound.

The primary function of this device is to keep Prarvis' elemental balance in equilibrium. If fortified, it moves towards order, retarding the process of growth. If damaged, it moves towards chaos, freeing some of the loose elementals which will cause minor destruction to the planet. The latter happened around -1,000, when the Brotherhood of shadow magic-using ogres, led by Il'grogg, led their Imperator Gilthal'torth to the throne to try and claim it for their Forerunner, Cxuirva.

Trivia

 * It is based on the Crown of the Elements from Warcraft, as Draenor/Outland is roughly analogous to Prarvis.
