Idol of the Storm God

From publisher blurb: On the Brackish Heath, the southern tip of the continent, desperate dwarf treasure hunters struggle to recover an ancient hobgoblin statue. The beating heat of summer, the buzzing of gnats, the stink of the salt marshes and the treacherous mud make this expedition a challenge for even the most experienced adventurers. Prepare for a journey of grit, and grid exploration. This story can take place in any warm or tropical salt marsh, but is designed to take place in the Brackish Heath in Bakkesat.
