They're called Súilo(s) and are powerful beings with eyes dotting their bodies (primarily chest/ears/wings/palms). Those on their face do not open save for extreme instances of power output and resemble nebulas when open. Each one commands over some sort of craft, which can be anything from an element to a concept (will, luck, etc).

They sometimes forge soul contracts with mortals, similar to demons, but these can be good or bad. Their tails are long and thin/wide, resembling trains/skirts that vary in length.

More info to come I guess.
