I sort of have a HOL-self. She doesn't really turn up very often when I'm chatting to you guys (this is all me the person) but I do picture her when thinking about the imaginative aspects of HOL, like when I have to write for a class, an activity or a roleplay.
Sky is actually a character from a novel I wrote when I was in my teens - I was lazy when signing up for HOL and used her. It's odd because now I both do and don't associate my HOL-self with that original character (I suppose my fictional HOL self might be an alternative universe version of her, if you want to get technical)
Anyway, enough of that weird metafictional stuff. Sky is small, lightly built and blonde. She's confident and exuberant - she loves to show off her wit. She's kind, imaginative, fiercely protective and still hot headed, even as a professor. She comes from a pureblood family of academics and musicians but her own heritage is halfblood, as her mother is muggleborn (no joke, I had to do a family tree for a class.... it is extensive). She likes charms the best because she loves how useful, artistic and subtle they can be.
