Spirits

Spirits are incorporeal beings who always seems to glow softly with moonlight no matter whether there is no moonlight visible or it is day. Most of their colouring and colours are along an array of cool colours and they have the finest fraction of substance, just enough so that they can float and glide in the air and land on bare earth with the weight of a feather yet pass through all substances other than themselves with ease. They take the human form as their usual self, but can transform into whichever shape they please.
