Karraden

A Karraden is, along with demon and wisp, one of three forms a soul can take after its host expires. Unlike the two previous Karradens are invisible in all ways and it is believed they have no physical form whatsoever and are just souls floating around the world.

Behaviour
Karradens are similar to ghosts in real life outside of the Randomness Universe. They are invisible entities whose only existence has been revealed through experimentation in space, revealing orbs of energy moving around. Karradens cannot communicate verbally but can through affecting various voice-related machinery. This causes wave-like sounds to be heard and it appears Karradens use morse code to communicate.
