Throne of the Gods

"It is said that somewhere there is carven from the heart of a majestic mountain a massive stone chair, inlaid with mosaics of ivory and precious metals and set about with gems, a throne upon which certain gods actually sat when they walked the world. The Throne supposedly is within a great cavern, a part of the mountain’s core, so as to be immobile and immovable. Anyone daring to seat himself or herself upon this chair is subject to the effects, and may gain benefits from the Throne’s magic." - Gary Gygax
