Arvandor

Arvandor was a realm in the first layer of the Outer plane of Arborea in the Great Wheel cosmology. In the World Tree cosmology, it was the second root of the World Tree. It was covered in lush forests, massive mountains, perfectly clear streams, placid lakes, and an ocean called the Sparkling Sea, as befitting of the home of the Seldarine. Each one of the elven patron deities maintained a realm on this plane. None of these realms had a border and each one seamlessly melded into the other with absolutely no discernible borders apparent.

Hanali Celanil maintained a portal to Sune's realm in Brightwater, and Erevan Ilesere maintained one that led to the realm of Hlal in Dragon Eyrie. A portal to the House of Nature, maintained by the whole pantheon, stood at the shore of the Sparkling Sea. The eladrins had a portal to the Gates of the Moon as well.

Inhabitants
The celestial realms of Arvandor and the Gates of the Moon were the only two planes where the elflike eladrin dwelt in significant numbers. The eladrin were not servants of the Seldarine, but they respected and generally cooperated with them in everyday matters as well as urgent ones. When an elven deity required a more powerful representative to travel to another plane, a deva or angel was usually called upon, rather than the eladrin, thus a multitude of celestial creatures made their home there. Gwynharwyf was also known to wander between this plane and the Gates of the Moon.

Petitioners
The petitioners of Arvandor – even those few who were not elves in their mortal lives – all appeared as handsome elves here, however their appearance was more exaggerated and fey-like than that of the elves of the Material Plane. These petitioners spent their time enjoying the eternal tranquility of Arvandor.

Realms of Arvandor
Arvandor was a vast, infinite expanse of pristine wilderness stretching from the boundless mass of the Sparkling Sea to a range of snow-capped mountains. While each deity claimed a portion of the realm, the majority was shared by the entire pantheon and with the eldarins.

Aerie
Aerie was the divine realm of the goddess Aerdrie Faenya, it was a glittering palace of clouds floating high on the otherwise crystal-clear skies above the forests and mountains of Arvandor. Celestial eagles and rocs made their home there, along with elven and avariel petitioners, celestial elves, and angels. Since the Spellplague when Aerdrie Faenya was revealed to be in fact Akadi, the queen of air maintained her realm on Arvandor, where she sometimes spent time.

Crescent Grove
The center of Arvandor was the great palace Crescent Grove, the home of Corellon Larethian and Sehanine Moonbow. Crescent Grove was a flawless union of nature and artistry, uniting white marble pillars and walkways with towering white-barked trees. At the center stood a tall tower called the Overlook, which offered a breathtaking view of the entire plane. Many petitioners of Arvandor spent their time here, reflecting in quiet contemplation and enjoying some undisturbed solitude.

Elavandor
This palace built of coral gold and veined marble at the bottom of a chasm in the Sparkling Sea was the home of the Dolphin Prince, Deep Sashelas. It was home to celestial dolphins and whales, great schools of fish and tritons swam along side the sea elf petitioners of the plane.

Pale Tree
This grove surrounding a wondrous white tree with silver leaves was the realm of Solonor Thelandira.

Rumors & Legends
It was rumored that the realm of Alfheim was once a part of Arvandor, but gradually slid into Ysgard as its inhabitants began prioritizing honor and survival.
