Magpie Windwitch

Action Girl
Adventurer Archaeologist: When she's not too busy fighting demons, she also explores temples, collects rare spells, studies other faerie cultures...
Book Dumb: Subverted. Despite Magpie never having attended an actual school, the "archaeologist" in Adventurer Archaeologist ensures that she has more general knowledge than most of the other characters.
Braids of Action: Although they come undone in the style of Slip Knot Ponytail.
Dual Wielding
The Herald: For Talon.
The Heroine
Little Miss Badass: She's a "slip of a girl" and kicks butt after butt after butt...
Smitten Teenage Girl: She positively adores Dusk.
Waif-Fu: Magic helps, but she can hold her own in a physical fight, too.
What Beautiful Eyes!

Talon Rathersting

Good Scars, Evil Scars: Talon's hands end up scarred from being badly cut while holding onto the tether around Magpie's waist.
Handicapped Badass: Talon can't fly, which is more or less like not being able to walk. That being said, even Magpie is impressed with his acrobatics.
I Just Want to Be Normal: Talon's lack of functional wings gives him a lot of angst at times.
The Lancer: While he and Magpie usually get along just fine, when she's putting herself in too much danger or being impatient or insensitive, Talon (and Calypso-it's a two-man job) reins her in.
