Asgardian Pantheon
The Asgardian Pantheon was a tight pantheon of gods residing chiefly in the divine realm of Asgard on the first layer of Ysgard in the Outer Planes. They were sometimes called the Norse pantheon and other times the aesir. With the exception of Tyr, the god of justice, the members of this pantheon were little known in the Realms and had no influence or power to grant spells in Realmspace.
Description
Technically, the gods of Asgard were the aesir, and the gods of the neighboring realm of Vanaheim on the same layer were the vanir. However, there was a good deal of marriages and mixing of blood between the two groups of powers, and so many scholars considered both to be the collective whole of the Norse pantheon.[2] The aesir were properly the family of Odin, while the vanir were better considered "cousins". The two separate families had a history of feuds.[6] The two groups maintained a treaty that stipulated that Frey and his sister Freya, of the vanir, must spend part of each year living in Asgard among the aesir.
Thor, the norse god of thunder
To some mortals, the Norse pantheon seemed like a rowdy group of Deities, relative to other pantheons, but they had a strong leader in Odin All-Father. This did not by any means imply that all members of this pantheon followed Odin's orders, but they all shared a unifying goal of maintaining their powerful realms on the first layer of Ysgard. Despite their chaotic mindsets, they were organized enough to hold the largest divine realm in Ysgard and were the most powerful group of the whole plane.
In addition to Asgard and Vanaheim, the Norse powers also controlled much of the realms of Alfheim and Jotunheim. They also controlled and defended a unique means of planar travel known as Bifrost, or the Rainbow Bridge, which could connect to any location on the Material Plane. Bifrost was their own creation and was strongly protected.
The Norse powers were served by a host of valkyries and einheriar.
Legends claimed that the World Ash, Yggdrasil, was the true source of the power of the Norse gods and goddesses, and it was prophesied that Nidhogg would eventually gnaw through the tree's roots, leading to the fall of the pantheon.
Many of the pantheon's members enjoyed exploring the Material Plane in disguise as mortals.[
Most of the members of the pantheon shared an outlook that held that bravery was proven by the endurance of pain, and, as a result of this, in the realms of Asgard and Vanaheim, many aesir and vanir did not permit healing spells to function. (The Norse powers, in general, paid more attention to magic performed on their plane than other Deities did.)
