Hellfrost Region Guide #1
From the publisher:
Across the northern continent are many places of wonder. Some are geological, carved by wind and etched by rain over the eons. Others are architectural splendors, worked by living hands. A small few are elemental loci, concentrated places of magical energy for one of the four elements. This supplement is concerned with a fourth category—sites inhabited by spirits or elemental beings.
Contained within are guidelines for creating sacred places, fully detailed examples, a new minor deity (Gullveig, god of brewers), and a new monster, the much feared dread wraith.
