The following is taken from http://www.geocities.com/Area51/Chamber/2596/powers/Eldath.html. This is not definitive, and much of the page is gibberish, but it gives some additional info on the deity and her followers.

Eldath is completely neutral to the point of extreme pacifism and nonaction, even when threatened. This is one of the reasons that Eldath is almost a forgotten power, in that most worshipers think of Mielikki or Silvanus first. Like Mielikki, Eldath serves Silvanus. Eldath has three types of priest that venerate her, clerics, druids, and specialty priest, called "Peacemen" and "Peacewomen" in the faith. The clerics and druids serve Eldath without the limitations against harming others (see below), but are encouraged to conduct themselves in a fitting fashion as put forth by their god. Priest of Eldath cannot fight, except to defend themselves and those with them. They may not initiate attacks, charges, or ambushes. They are pacifists. Those priest of Eldath who seek to bend the will of the goddess to their own ends will soon find themselves without clerical abilities.
