O, Solstice Tree
I made sure to look up how the old Solstice celebrations were done. The decorating of the holiday tree did, in fact, start with the entrails of fallen enemies. I doubt there were lights, however.
Personally, I prefer cookies after a delightful evening of intestine stringing.
 
    

When evil spreads across the land, and darkness rises and the monsters roam. When the creatures of the night make beautiful music, and the things that go bump in the night go bump with greater enthusiasm. When the world is in peril and is in need of a hero...

These guys are, sadly, the best the world can hope for. These are the adventures of the heroes of CVRPG. They mean well, they try hard, and occasionally they do the impossible...

They actually do something heroic.
