Mount Olympus

Mount Olympus was an enormous cross-planar mountain that connected the Prime Material plane with the Outer Planes that were important to the Greek pantheon via the Astral Plane.

Description
In the region of Arvandor within sight of the mountain, Mount Olympus was the most prominent feature of the landscape, rising above the rest of the plane. It was believed by the Fraternity of Order that visibility from the mountain's peak could extend as far as in any direction. Travelers claimed that even the other two layers of Arborea, Aquallor and Mithardir, could sometimes be seen fom the summit.

The slopes of Olympus had a rich landscape of woods and rocky terrain. The southern slope of the mountain was a pastoral region with olive groves, vineyards, apple and orange orchards, and sheep grazing areas. It was considered the easiest ascent route. Some of the caverns under the mountain were beautiful, filled with colorful lichen and lit by luminescent rock. The caverns sometimes opened into enormous chambers that defied perception and did not seem at all like an underground environment. Other caverns were damp and small, littered with bones and permeated by rotting smells.

Cosmography
The slopes of Mount Olympus were rooted in the divine realm of Olympus in the first layer of Arborea. It was the most prominent feature of the realm. At its base, twisting caverns cut through the stone at the veins of the mountain into the Lower planes of Carceri, Gehenna, and Hades. Entry points into the planes could be found at round, colored portals, in a similar way to the planar connections of Yggdrasil. However, unlike the World Ash, the portals to and from Mount Olympus were well mapped and did not shift over time.

Mount Olympus connected to multiple worlds in the Prime Material plane, which were accessible via hidden paths along the mountain. On Toril, the mountain was located on the island of Achea, which lay several hundred miles from Faerûn. In order to reach Arborea, travelers needed to climb the mountain to the very summit. The Torilian manifestation of Mount Olympus had an elevation of.

Defenses
Although all the portals leading to and from Mount Olympus were open to anyone trying to cross them, many of the secret paths leading to other planes from the mountain were guarded by creatures in the employ of the Olymian deities. Some of those pahs were only accessible to worshipers of particular deities, while anyone else trying to use them was instead redirected to Hades.

Inhabitants
Mount Olympus was the home of most deities of the Greek pantheon, who held vast halls and temples on its slopes.

The mountain was primarily inhabited by nymphs, satyrs, and sylphs. The caverns of Mount Olympus were inhabited by bacchae, oreads, and satyrs, among others.
