From publisher blurb:
An adventure for novice characters
Strange gods aren’t unusual in the darkness cast by the shadow of the Demon Lord. New faiths appear regularly. Most fade away on their own, or, in the most repugnant cases, their adherents are hunted and murdered by the good folk they offended or endangered.
The God Below is an adventure for a group of novice characters. In it, the characters investigate the temple of a newly emerged religion to determine whether the god Duvia is a benevolent deity or a threat to safety and the existing order. The characters complete the adventure when they destroy the horror unearthed in the temple’s bowels.
