Will o' wisps are some of the strangest and most unexplained creatures in the veil, often credited to being simply swamp gas and spontaneous combustion in the old world. They are often found in the hallowed woods in the new world, though, and definitely of some sort of being. They are rarely seen, though, and usually only lead someone through the forest and out of danger if they are lost. It is said that if you see one out of your window, the first step towards your fate will begin that day, though it is impossible to prove if this is true. They are commonly seen in groups of four, though the most famous group was a group of three.
