The Seldarine is the elven pantheon of gods who resided in the astral dominion of Arvandor under their leader Corellon Larethian. Similar to the Faerûnian Pantheon, each deity holds a Portfolio, which is a literal as well as figurative
list of the aspects of existence that the god represents and holds
dominion over. The pantheon is hierarchical, with power, influence, and title determined by the number of followers and
their relative piety; however, The Seldarine only has one Greater Deity, Corellon Larethian. He is the recognized leader and the most powerful of the elven gods, but he does not demand the fealty or obedience of any below him. The Seldarine are free to choose their own paths and make their own allegiances but all have chosen to follow Corellon Larethian because of his strength of leadership and high moral standing.
Greater Deities exhibit almost unlimited power,
have Portfolios that encompass fundamental aspects of existence, and
have the most followers, who usually number in the millions.
Intermediate Deities have considerable power but pale in comparison to
their Greater counterparts and generally have followers in the hundreds
of thousands. Lesser Deities are usually servants of stronger deities
and have followers in the tens of thousands. The key distinction between
True Deities and other less powerful deities is the ability to grant
spells to their followers.
Demigods are entities that were either born of the union between a True Deity and a mortal or were born mortal and later achieved godhood. Like other deities, Demigods carried their own Portfolios, but they were usually much more limited in scope. Demigods generally had followers numbering in the thousands, and those followers usually had some sort of common identity between them, such as class, background, or profession. Exarchs are the most powerful servants, agents, and champions of deities and other extremely powerful entities. Some Exarchs are deities themselves but most are mortal beings who have achieved unprecedented power in life and have been recognized by a deity as worthy of regard and servitude.
The Spellplague has had curious effects upon The Seldarine. Many deities lost their divinity, becoming mortal again albeit extremely powerful mortals. These deities remain in the grace of Corellon Larethian and serve him as exarchs. Some deities seem to remain powerful and active; however, the distinctions between themselves and their counterparts in the Faerûnian Pantheon have become blurred.
