''a kingdom beyond the grassy plains of the north.''

The north is an icy realm of ice and .. ice water. No grassy plains there, for grass you'd have to look to the center of Borhilon and to the east, where steppe plains are aplenty and Tatar/Turk-like horsemen roam the area. Further east are some.. foreign countries/kingdoms, but I haven't decided their culture yet so...

Besides that your character is in Volynia - the great city - right? No other characters are there and I was mostly adding that to the description to give people an idea of possible locations to visit, or have visited in the past. I'm fine with you being there but it'd be a lonely existence.

Perhaps you had to flee from Volynia, and escaped to the Whitelands, where nobody really knows you (yet?) and she has to face a decision to start a new life or continue her thievery?
