The small town of Moonstair lies on the far frontier of the barony of Therund. A central stop on the north–south trade road, Moonstair is the site of an ancient portal to the Feywild. East of the town lies the dangerous wilderness known as the Trollhaunt—a maze of swamp land, thickets, gullies, and forested ridges. In ages past, this area was part of a land called Vardar, a violent realm of troll war-clans and the monsters that served them. Vardar fell into ruin centuries ago, leaving only dank barrows and a few fog shrouded stone forts to mark its existence.
