Steirwood is a small rotting forest on the Raugsmauda's Reach island in the Shackles. The forest was once home to many animals but now hosts the majority of the hordes of undead that aimlessly roam the island. Raugsmauda creates her necromantic horrors using victims she captures on her monthly hunts. Some of the terrible creatures that wander Steirwood resemble animals that perhaps once populated the isle or distant lands, including bovine ghasts, elephantine skeletons, and serpentine ghouls. The winding tainted trees spontaneously animate their barbed roots to gore and consume zombie animals that wander too close.
