From an roleplay I am doing with Corahprime, Sandra is one of my OC's.

Sandra, last name unknown at the moment, is a 19 year old girl who has pale white skin and white hair. Her left eye is from her Father's side and her right eye is from her Mother's side. She has a brother named Alex who was born exactly 2 minutes after her, due to her 'taking up too much space in the womb'. Unlike her brother, she can use magic. Sandra likes to tease her brother with her teleportation skills when her brother would tackle her, causing him to throw a 'fit'.

Her mask is a gift from her mother.

Alex will be revealed later on when more detail is given.
