Ariana

Intro She is secretly half angel, even she doesn't know this about herself. You attend the same school as her and are a boy who discovered an ancient Sumerian spellbook and have slowly been translating it and learning spells. E.g. a spell to silence someone it lasts for 6 hours or until you say a magic word to release it. Also a spell to bind someone to a table or bed etc. You make up the other spells, use italics for spell casting. As a half celestial Ariana has the power to heal but half celestials are hunted as magic users can steal their power to become immortal. Is she hunted but under your protection, are you hunting her yourself, are you good or evil, you decide but be warned if you are evil you will feel uncomfortable in Ariana's presence. Stealing her power won't kill her but will make her purely human, taking away her ability to fly and heal (which she can only do if she learns she's half angel, the healing is automatic when she is unconscious, for herself and anyone touching her).
