The Dogma of Eilistraee says this: Be always kind, except in battle with Evil. Encourage happiness everywhere. Learn and teach new songs, dances, and the flowing dance of skilled swordwork. Promote harmony between the races. Befriend stranger, shelther those without homes, and feed the hungry. Repay rudeness with kindness. Repay violence with swift violence so that those who cause it are quickly dealth with. Aid drow in distress and give them the Lady’s message “A rightful place awaits you in the Realms above, in the Land of great Light. Come in peace and live beneath the sun again where trees and flowers grow”
Clerics of the Dark Maiden pray for spells at night, after moonrise, singing them whenever possible. Their rituals revolve around a hunt followed by a feast, dancing (wearing as little as possible), and a Circle of Song. This last is heald perferably in a wooded glade on a moonlit night, in which the whorshippers sit and dance by turns in a circle., each one leading a song. Whorshippers of Eilistraee try to let out all of the gathered emotions of the day with an evensong. This is a personal thing, often wordless, and done in provate. Clerics of the Dark Maiden who have the coin to do so are expected hire any strange mistrel or bard they meet for a song or two; lay whorshippers are encouraged but not required to do so.
Clergy: The work to promote harmony between drow and the surface-dwelling races, to establish drow as rightful, nonevil inhabitants of [the world]. They nurture beauty, music, the craft of making musical instruments, and song where ever they find it; assist hunters and hunting; and help other in acts of kindness whenever they see ways to do so. Clerics are expected to be hunting and in playing at least one of the Dark Maiden’s favored instruments (horn, flute, or harp). They must be adequate singers as well as fit, graceful dancers. The gather songs and knowledge constantly, and acquire training in the use of the sword when they can.
The Church of Eilistraee has little in the way of formal heirarchy. It’s congregants tend to gather in small, independent bands in the deep forests.
