Dark Scar

The Dark Scar is a scar on Rose's back that was given to her by Sage when she was visiting the Dark Realm for a Royal Meeting (which is why he was banished to The Between Realm). It prevents her from using serious magic, and pains her from time to time (although she is very skilled at hiding her pain). She is very self-consious (especially around David) so she uses The Special Gel to hide it
