Hm..I do not believe that I have uploaded any pictures of these fellows yet. The Breveii are eddas (kind of like 'gods', although more accurately, spiritual entities) who basically cull any errant spirits. They are physically blind, as they exist in a purely spiritual sense, and thus sense their world in a sort of telepathic manner. For them, the world is an endless, flat expanse of bleak rainfall, and they sense errant eddas by the way in which they disturb the rainfall. I guess you could almost liken it to super-sensitive hearing, noticing that the rain suddenly falls differently on something.
