A minor, nearly forgotten member of the Seldarine, Alathrian Druanna is the goddess of writing, subservient to Labelas Enoreth in his role as keeper of history. Because of her portfolio on writing, she has come to hold the fields of conjuration, geometric, and runic magic as well, although only a small number of elves still follow her tenets.
Another of the minor Seldarine deities published originally in Dragon #155 and updated in #236, Naralis is a god of healing and death. He serves Sehanine in this capacity, while his priests often serve the elven nations in classic medic roles.
One of the younger elven deities from the pages of Dragon Magazine, Araleth Letheranil is the god of starlight. He is an adventurous deity that keeps darkness at bay, and opposes many of the traditional enemies of the surface elves, especially drow. These traits have made him particularly popular with the members of the Elven Fleets in wildspace.
One of a number of minor elven deities who appeared in the pages of Dragon Magazine, Tethrin Veraldé had an abbreviated Faiths & Avatars style writeup in Dragon #236, which I have expanded upon.
