"Bloodwood of the Cruor Circle" is an alseid and blood hag lair suitable for four or five 10th-level characters. This adventure can be completed in a single session. The Cruor Circle, a coven of dark druids led by a blood hag, has taken over control of the local alseid herd with the power of the blood. Within the forest, those who do not make proper sacrifices are stalked by the alseids and taken to the Bloodwood. Within the Bloodwood, captives become blood sacrifices, empowering the creation of sap demons, blood ponds, and other twisted products of the dark druids.
