By the Light of the Whispering Flame

From the publishers blurb:

Welcome to the city of Collant, Jewel of the Serrated Coast, powerhouse of magic and industry. But when the city’s corrupt leaders make a bargain with a sealed demon, cataclysm strikes and the city’s reliance on tainted magic exacts its toll, wrenching it from time and space. Scars in the planar fabric now tether Collant to the shadow realm of Nowhere, and the demon’s return is at hand.

But hope is not yet lost. The Order of the Whispering Flame has begun to wield their holy fire to push back the encroaching darkness and cauterize the Scars. To complete their mission, they now seek brave adventurers to bear the flame and press in to the lost depths of the city to finish what was started.
