Rain Festival is a festival celebrated by the Druids within the Circle of Stones. The druids perform a live human sacrifice, burning them inside of a wicker basket hanging above a bonfire in an attempt to bring weather to the islands. When a Rain Festival has ended, the druids return to their village to sleep, leaving the bonfire to smoldering in the center of the circle. The ritual is one of the most ancient and powerful of all spells--a blood sacrifice for fertility. For rain.
