When encountered during Charting the Millennium Woods and Once More Into the Millennium WoodsWillow Creek was a ruined Fey town in the Millennium Forest.

When visited much later, during Smells Like Flower Spirit, the town was found rebuilt and repopulated. A small stream runs close to it, where it presumably got its name from. 

Willow Creek belongs to the territories of XXXX, a minor Fey Barony that includes the northernmost tip of the Millennium Forest. Agra's Manor is the private residence of the Baron or Baroness; before she was slain, Lady Agra used to hold this title on Aseron's Court.

Villagers of Willow Creek used to visit Maranthede, but these visits ceased, presumably when the town fell. One of them would steal the talking tree's leaves, for an unknown purpose, before others caught the thief; the tree itself did not mind, but was puzzled by this. Today, the inhabitants of the restored settlement are aiming to reestablish their relationship with Maranthede.

At the bottom of a chasm that opened in the middle of town, there is Willow Creek Ruin.
