Lassu

Lassu are strange creatures. They appear as serpents with feathery wings, a strange bulbous rattle, and an oddly human head. They have been known to display supernatural powers, such as mind reading, clairvoyance, teleportation, and the ability to fly though solid objects. They do not seem to be confined by the same laws of physics which govern the rest of the universe, leading some paranormal researchers to theorize they are multidimensional entities capable of moving outside of space-time. As to who they are and what their ultimate purpose is, no one can say.

Drowchu

Drowchu is a type of small, land dwelling protoplasmic entity. Drowchu are not ghosts in the purest sense, because they have never inhabited a physical body. They tend to hang around isolated areas, ruins, ghost towns, etc, and are generally harmless unless provoked.
