Original poster beat me to the "Former ThreeEye Junkie on the Turnaround" concept I was kicking around, so I'll toss some of the others out here. . .
Fire-Slinging Winter Changeling - Basically the kind of character that doesn't WANT to go Winter but still finds himself answering to certain "instinctual" calls of his nature.
Little Talent with Big Britches - I haven't decided on what kind of non-wizard spellcaster this will be, but their motivation is "I wanna be a Warden someday!" (Not sure if this is a normal Aspect, a better way of wording the High Concept, or even a Trouble Aspect.)
I was rather tempted to add the trouble aspect of "Indebted to Power" and adding sponsored magic to the mix. Hrmmm. . .
Reenactor Running With The Pros - A Vanilla Mortal (or at least one who STARTS as a mortal) who reenacts one (or many) battles and lifestyles of the past, but has been roped into supernatural politics due to the supernaturals present at these events.
(This one is left wide open, as this character can be a Wild West Gunslinger, a Civil War Soldier, or even a Chivalrous Knight, among other options).
Have fun!
