OriginGreek mythology

A muse is a term for a system member that specifically works to inspire a creator, either directly or indirectly. Some muses are more proactive than others and work as a creative partner to another, assisting with artwork in ways large and small. Other muses are generally passive and the inspiration they give a creator is through their own existence or actions.
