The Hunter's Game (5E)

From publisher blurb:

The Hunter’s Game is a 4th-level adventure that leads the PCs into the foreboding Dyrgalas Fens, a temperate swamp in the Harwood Forest nestled between the Wolf Hills and Low Hills. Dyrgalas Fens is overrun by an eclectic collection of malevolent monsters, xenophobic humanoids, and foul beasts. When some of the region’s finest gentlemen and ladies never return from their excursions to the Answin Hunting Lodge, the PCs must investigate their mysterious disappearances. The journey leads them into the figurative heart of darkness, taking them not only deeper into the dreadful Dyrgalas, but also plunging them into the harrowing abyss of hatred and greed.
