Feasting Hall of Cayden Cailean

From PathfinderWiki

In Mivon, in the River Kingdoms, there is an unusual hill. It is devoid of vegetation, and has a ring of standing stones on its summit. At irregular intervals, these stones transform into a feasting hall from which comes music and laughter. It is said that those who enter on these occasions can join in the revelry. Some say that this is the Feasting Hall of Cayden Cailean himself, Cayden Cailean being the god of ale and wine.

In the morning, the standing stones replace the hall once more, although the hillside reeks of ale and wine. However, more ominously, last time there was also a large quantity of blood among the stones.[1]
