From publisher blurb:
YOU HAVE A NEW GAME! YOU NEED NEW MONSTERS!
Fires are as natural and regular as seasonal rain, clearing detritus from the ground, opening canopies to allow light to shine through, and even triggering seeds to mature and spread. When a forest or other ecosystem approaches the end of its growth cycle, the flamebearing deerlike creatures known as rinhs appear, surveying the habitat and deciding whether the time has come to burn it down and make way for new growth.
The impact their actions may have on nearby settlements is not part of the rihn’s concerns.
