Duskwood

This tangled haunt of Stirges, Predatory Trees, Giant Spiders, and Enormous Snakes is still widely visited for many kinds of rare plants prized by herbalist's, spellcasters, and alchemists. The wood is also known for several pools said to be capable of repairing magic items: The Vauntagar, a magical binding-ward, keeps a cycle of monsters alive to guard the pools. When the active monster is severely injured, it shifts to an extra-dimensional space where the others live, and a fresh creature is sent to take its place in the wood. Aside from the Vauntagar creatures, at least one Beholder haunts the forest.
