Umbrian Flats
A system-neutral fantasy setting guide detailing a wilderness along the Udunilay and Ondavar Rivers, beneath the lingering shadow of Aufstrag. It describes the region’s terrain and history, including hidden halfling communities, elves beyond the material world, and monsters that inhabit its forests and sodden lands. Adventure hooks support exploration of a dangerous frontier where the conflicts of the Winter Dark still continue.
