Nidor, a world given life by titans
Cult of the Red Rain
A reptilian based cult known to worship Lamashtu. They drain blood from victims of horrid murders. Typically they target half elves. Through dark incanations, they create unholy liquids that can be used to desecrate land, buildings, etc. According to texts the party has discovered, the current ruler is a serpentfolk known as Saint Naris, an elderly male who is very much attuned with Lamashtu’s goals.
The cult seems to be readying for a large event, as evidence by the increase in half elven sacrificies.
