Here's my two characters:
Appearance: A bit small for her age, with olive skin, dark eyes, and dark, messy hair kept short. Wears loose-fitting jeans and a plain long-sleeve, at least in this instance.
Personality: A bit of a loner, and tends to interact through witty quips and sarcasm.
Fears: Tight spaces, being trapped, injury
Appearance: About average height with an athletic build and long blonde hair. Tends to wear sporty/trendy clothing; in this case leggings and a sweatshirt.
Personality: Generally very bubbly and friendly, with a habit for teasing and a bad habit of letting her strengths get to her head.
Fears: Failure, powerlessness, the dark
I'll probably get this started today or tomorrow, since it doesn't seem like anybody else will be joining in.
