Arborea (/ar-bɔːr-eɪ/ ar-bore-a)

The Olympian Glades of Arborea, sometimes simplified to just Olympus or Arborea, was the Outer Plane embodying the chaotic good alignment. Its beauty was almost overwhelming, the landscape embodying the lovely and peaceful, and the passionate and wild, all at the same time.
In the Realms, the entire plane was known by its elven name, Arvandor, since the Olympian powers were not known there. Its many names failed to truly capture its scope, Olympus and Arvandor only being two massive realms within it, and Arborea being a misnomer given its many environments.

Arborea! A more wondrous place I could not ask for. Nowhere in my mortal life did I find a place of such great passion... such splendor... The beauty of the land, the people — magnificent. I tell you truly, I miss it even now!

— The spirit Asonje

Arborea was first and foremost a land of emotions, running high, deep, and far.These were not all positive emotions; Arborea was a place of powerful love and hate, where rage and joy were equally common and equally honored.
Arborea was most accurately described as "boisterous", favoring melodrama as opposed to stoicism. Vibrant energy filled the plane, the air tingling with excitement and constant anticipation in the literally emotionally charged atmosphere.
Greed, envy, lust, and wrath were strong on Arborea, and emotions could be released with dangerous consequences, but that was not to say that the plane was an evil one. Arborea was as much a plane of good as it was one of chaos, disavowing the notions of those who saw chaos as destructive disharmony or a tumultuous maelstrom. It was a realm of individuality and independence, a good-natured place of celebrations and strong desires where personal freedom was paramount. As strong as the vices were, charity, justice, love, and kindness were equally rampant on Arborea.
Arborea's larger than life aspect was both figurative and literal, the big emotions reflecting the big plane. The sheer extravagant size of everything simply couldn't be understated: every craggy mountain was stupendous, every ravine unbelievably deep, every lush forest filled with monstrously huge trees, every ocean unimaginably deep, every river mighty, and every plain a wild stretch. Never doing small, Arborea's immensity made it difficult to traverse due to steepness and distance.

Layers

Arvandor - Olympus

The layer of Arvandor was sometimes referred to as Olympus. Its two realms—so vast and influential that their names became synonymous with the plane and the layer they occupied—coexisted with little conflict: Olympus, home of the Greek pantheon, and Arvandor, domain of the Seldarine, court of Corellon Larethian, The Wind Dancer.
Arvandor contained the great forests for which Arborea was known, towering assortments of monstrous maple, birch, oak, lindens, and other deciduous, broadleaf trees rivaling the redwoods of the Material Plane in height. Clear glades were as common as briar patches and tangles, but paths snaked through what undergrowth existed.

Aquallor - Ossa

The second layer of Arborea was also known by many names; it was Ossa to the Olympians, Aquallor to the elves. Regardless, the layer was an endless, emerald ocean. It was disputed whether or not the plane had any land above surface, whether in the form of scattered islands or coastlines, but even stranger was the depths, the seas of Ossa were ironically shallow for a plane of otherwise great size, no more than 3 ft (0.91 m) deep over most of the realm.

Mithardir - Pelion

It was a borderless plain of fine, chalky grit, a white desert nearly devoid of all life. The particles in the air were as cold as ice and so easily mistaken for snow at first glance, though snow was also potentially present along with the sand. The desert was neither hot nor particularly cold either way, just temperate in most places, but it was extremely dry.

Inhabitants

The most common celestials in Arborea were the eladrins, natives to Arborea just as demons were to the Abyss. The wild, fey-like celestials constantly moved from place to place on the plane, exulting in their own free existences. The best known and most commonly encountered breeds were the ghaeles, a type of celestial eladrin, that were often found hunting through the wilderness.
