City of Brass
The Holy Lanterns are an aggressive, proselytizing religious order with great power in the City of Brass. Their main symbol is fire, specifically a gold lantern bursting with red fire.
The Lanterns believe that they know the only path to salvation, which requires dedication and sacrifice to the Gods of Fire and Light. Sacrifice takes many forms, including giving up wealth to the temple and, some fear most of all, giving up one’s spiritual energy (that is, one’s soul).
Worshipers believe that all of these sacrifices endear them to the Gods of Fire and Light and preserve a place for them in the afterlife.
The party accosted a fire-and-brimstone preacher who was camped outside the front doors of the commune. They eventually enspelled him to get rid of him, but it won’t be that easy.
