Muses or Idols are characters who inspire others. Normally seen as positive, Muses can easily become negative if twisted in a manner similar to Genies. Often appearing to individuals or groups, a Muse inspires them via horrific events of circumstance.

A good example of a Muse is someone who performs grisly misdeeds which others take as inspiration for their work, whether they become Copycats or something else entirely (such as horror writers gaining inspiration from Demons who showed them grotesqueries used in their work).

Muses will see their misdeeds as a type of art and share their "gifts" with those unfortunate enough to be around them. Usually they are feared by everyone around them due to idolizing things traditionally seen as taboo in society, though exceptionally twisted or desperate individuals may willingly call upon such Muses when in need of inspiration.
