Mount Olympus (Dungeons & Dragons)

Mount Olympus is a fictional location in the Dungeons & Dragons fantasy role-playing game.

The first edition Manual of the Planes by Jeff Grubb describes Mount Olympus as an astral landmark, noting that it is normally encountered by travelers from worlds that worship the Greek mythoi, but travelers from other Prime Material worlds can encounter the mountain. It is a long-standing conduit from the Outer Planes to alternate prime worlds that was created by a group of deities and worshippers in the Prime Material plane. Mount Olympus is a huge mountain that links the Greek pantheon's part of the plane of Olympus with the Prime worlds that they are strong in. It has exits on the lower layers of the planes of Gehenna, Hades, and Tarterus. The mountain is a solid and permanent conduit that weathers the waxing and waning of faiths in the Prime Material and the fortunes of gods in the outer planes. The traveler is confronted with a huge mountain wall rising from the mist of the Astral and disappearing far into the distance. The traveler can then climb the mountain to the appropriate outer plane, descend to the reachable lower planes, or explore the alternate Prime worlds that the conduits touch upon. At the true terminus, the mountain ends in a color pool similar to that of a fixed portal. The traveler can then pass into the outer plane as if moving into an alternate Prime Material or the Astral plane. Yggdrasil and Mount Olympus are the best-known of the permanent conduits that link the outer planes with the Prime and with other nonlinear outer planes. The Greek pantheon gathered together into a common front to fashion Mount Olympus as a continuous conduit that reaches from the plane of Olympus through the Astral and into Hades, touching all the Prime worlds where the Greek gods are known. It is not certain that the Olympian gods forged this mountain; others claim that the Olympians are little more than inheritors and usurpers of a conduit that existed since before the titans ruled Olympus. The gods of the Greek pantheon have remained together in the same location, at the head of the mountain, for mutual benefit and defense. Zeus, the leader of the pantheon, maintains a great citadel of polished marble and gold at the highest spot of the Olympian Realm. The lair of Ares is a massive battlement near the portal to the Mount Olympus passage, mirroring that of Athena, who dwells in a passage on the far side of that portal. The plane of Hades is the foundation of Mount Olympus, which reaches the Greek pantheon in Olympus, and which reaches lower layers of the plane of Hades. The base of Mount Olympus reaches the plane of Hades in its third layer, Pluton, in the grove of Persephone, at the gates of the domain of the god Hades. The realm of the god Hades has gates and great walls surrounding the grove of Persephone, where Mount Olympus has its base and passes into the Astral.
