Blade Dancer Domain

Followers of Eilistraee value independence and choice as inviolate. Their clerics welcome and accept beings of all races who desired to see all people living in harmony, without pointless discrimination or wars, and worked towards that goal. They try to bring happiness and merriment everywhere they went, lifting people's hearts with kindness, gaiety, songs, jests, dancing, and revelry.  They respond violence with swift violence, thus quickly removing dangers and threats, so that the fewest might be hurt.

The worshipers of Eilistraee mostly consisted of those drow who hoped to escape the danger and darkness of the Underdark and Lolth's evil, taking back their place in the surface world. However, in line with her ideals, Eilistraee would welcome beings of all races (though, among her non-drow followers, elves, humans, and especially half-elves were the most numerous). They shared the desire of seeing all races living in harmony, without pointless discrimination or wars, and worked towards that goal (and those among them who were drow also fought to build their own place on the Realms above).

Eilistraean communities were often of matriarchal nature. However, differently from Lolth's, theirs was a nurturing matriarchy, meant to empower all—males and females alike— to thrive on the surface world, and characterized by a very loose hierarchy. In fact, the clerics of Eilistraee, commonly known as Sword Dancers, acted as an extension of Eilistraee's own motherhood of the drow, and took the role of teachers, protectresses, and diplomats. The priestesses aided their people to learn to live and forge their own path in a hostile world, and to rediscover a sense of belonging and community. They also protected their people from danger, and built a place for them to live by establishing friendships and relationships with other races. The Eilistraeans were also known to offer aid and shelter to those who came asking them (no matter the race), and even to actively travel to other places in order to bring food, cures, arts, and practical help where there was need of it and to those met along the way.

Many followers of Eilistraee, and especially her clerics, strove to learn and promote arts—with a soft spot for music and dance—as well as teaching them and passing along the knowledge of particular pieces, songs, or dances learned during travels or created by them. They would also take care of broken musical instruments, or craft new ones. Those who didn't know an art, were instead known to support bards by hiring them when they could afford it. This was part of their way to promote joy and merriment in their communities and during their travels.

That said, despite their efforts, the faithful of Eilistraee, were little known and poorly understood by inhabitants of both the Realms Above and the Underdark. Her worshipers were figures of myth and superstition and were targets of prejudice and wild mistruths. Some surface dwellers believed they were the disguised vanguard of the Spider Goddess's plan to take over the surface, while those drow who followed Lolth or other evil deities suspected them of being surface elf spies and saboteurs posing as drow as a prelude to invasion. Most non-elves could not comprehend the existence of a good drow deity, while surface elves were uncomfortable considering it, finding Eilistraee a threat to their doctrine that the dark elves were wholly to blame for the Crown Wars and other ancient tragedies.

Eilistraee was most commonly worshiped in Cormanthor among the drow there and in the Dalelands among the half-elves, and also in Waterdeep and Skullport. She also had followers (mostly humans, elves, and half-elves) living in Silverymoon and its surroundings.All her worshipers were typically of a good nature.

The Dark Dancer was worshiped through song and dance, if at all possible in the surface world under the moon (preferably in wooded places). Worship of her was usually accompanied by a feast.
