The Crimson Adventurer(Alchemist?)
Clarissa is known as The Crimson Alchemist though some also call her The Crimson Adventurer. She is an airhead and often gets other people who she has contact with to get in trouble.
She reveals herself as also being from 2000 years ago, same as Elyse. She is operating under a mysterious figure and cannot divulge any more information than she can, because she the entity will “punish” her for doing so.
