The Green Abyss

Welcome to Selva Oscura, where carnivorous faeries giggle from the shadows and swollen fungi dance in the gloom. In this feytouched layer of the Abyss, courts of demonic fey vie constantly for power beneath the twisted boughs of hungry trees. The ruins of fey palaces are picked over by carrion sprites while twisted hags plot their wicked schemes. And slumbering at the center is the still living corpse of an unimaginably ancient demon lord from which all this verdant madness sprouts.

This 400+ page sourcebook is intended to give DMs the resources they need to create an entirely different kind of Feywild oriented adventure from the ones they may know
