Valley of the Sunken Sun

From publisher blurb:

Hex 17.22 -- the Valley of the Sunken Sun -- features a goblin village in an abandoned manor house at the edge of the Lake of Abominations. A mutated carcass crawler dwells in a well at the center of the village and is worshipped as a god by the goblins. The book also contains optional combat maneuvers to customize fighting classes and provides rules for the creation of charms and fetishes -- minor magical items that lower-level characters can create.
