Fanghome

From publisher blurb:

Set among the ancient ruins of a fallen empire and standing on a bare escarpment overlooking the so-called Twilight Jungle, Fanghome is a relatively peaceful troglodyte settlement. Fanghome’s prosperity is built upon the Zji-Zji berry which the troglodytes have learnt, after a fashion, to cultivate and which they sell to those visitors brave enough to enter their fetid home. Not all is peaceful, however, in Fanghome for the troglodytes are an ancient race that once worshipped ancient, fell powers. Once such power has recently taken notice of the troglodytes and has begun to whisper dark dreams of power and conquest into the ear of its newest worshipper.
