Religion in Waterdeep

Waterdeep had a huge variety of faiths, and the odds were that if a deity was worshiped somewhere in Faerûn, it had at least a follower (or likely a wandering priest or two, and maybe a shrine) in the City of Splendors. The largest temples in the city were dedicated to Oghma, Tyr, Tempus, Gond, Selûne, Mystra, Silvanus and Mielikki, Lathander, Sune, and Tymora. There was also a large temple known as the Plinth, which was open to all faiths.
In addition to the temples, shrines to Chauntea, Lliira, Sharess, and Siamorphe (the last two were local divinities) could be found here. Additionally, there were secret temples and hidden shrines to most of the dark gods, often hidden away beneath the streets of the city. These included churches of Cyric, Talona, Umberlee, Shar, Auril, and a wide variety of the Beast Cults, including the Cult of the Dragon. In the years immediately following the Time of Troubles, Waterdeep had an active Cult of Ao; however, this later diminished almost to nonexistence.[citation needed]
There was also a temple dedicated to Baravar Cloakshadow located within the Warrens beneath Waterdeep.
Although the faith of Talona is considered misguided or bad, it does not mean small groups of lay followers cannot practice their personal faith. However, the building of a public house of worship to her is forbidden in Waterdeep. It is also illegal to form a public priesthood dedicated to her.
As of 1491 DR, a new temple to Valkur had already been built in the city. In the same year, the returned drow goddess Eilistraee was witnessed as she danced in the moonlight, near the walls of the city, up the road to Amphail. This led many of her followers to Waterdeep, with the goal of creating a shrine to their goddess within its walls. The project was supported by the Harper leading delegate Remallia Haventree.
