I need to brainstorm and think of a basic outfit for her default, than update this sheet.

Siyan is my mage on WoW. Shes playful, childish, a pyro and selfish. The only person she will listen to even a little is her older brother Mathius. Their parents died when they were young and Mathius raised her, he is very protective and probably sheltered her too much so shes childish and, and when she got herself into trouble he made it go away so she didn't have many consequences for anything she did, so she has never practiced self control. If she wants it she takes it, if something makes her mad she sets it on fire.

She specialized in fire because that is what her brother specializes in and she idolizes him. Despite that, when he is usually the butt of her pranks (i.e. setting on fire), but this is probably because they are usually on their own with just each other.

Another thing she gets from her brother is an inflated ego. Mathius thinks he and his sister are smarter and more talented than most everyone else. Siyan takes what Mathius says as fact so she assumes everyone she meets is below her.
