Aesa is a wonderful girl with a variety of personalities, all so different but all so likeable.
She can pull of any look she wants, any hair she wants, and look equally as gorgeous. She's problematic but she gets through her problems with a bit of coffee and a proper support system from her friends.
Or Æsahættr.
God-destroyer.
The name of the subtle knife in Philip Pullman's 'The Subtle Knife'. A knife with a blade so fine it can cut throughanything, including the fabric between universes.
