Poltergeists
In the midst of summoning ghosts, we noticed a fair few forming with a horn atop their heads! After further investigation, we determined these spirits to be Poltergeists. Poltergeists are known for being angry, dangerous spirits, that seek to do harm. However, these entities that came to us seemed to be only half poltergeist in nature. Sporting a chimera like split between naughty and nice, these spirits prefer mischief over mahem, and harmless pranks over harm. They seem to seek playfulness and joy in the homes that they haunt, and the people that live there.
