This is an idea I've had for a long time now, exploring the story of how a Wizard happens. On a whim last week, I began thumbing through my Burning Wheel books. I don't know why I didn't look to this system for this kind of story sooner, but it's a perfect fit.
A week later, and we have three freshly burned characters ready to begin their journey down the path of arcane mastery.
I plan on posting something from our sessions, either audio files or transcripts. I still haven't decided. I will likely collect material for a few sessions before taking this anywhere, but I haven't been this excited for a game in years.
