It's coming up on the end of January now, and I guess it's time to do this again.
Impress your colleagues, make your friends go "Whut??"
The Objective: A strategic and tactical genius, who will never be allowed into any military! (including Mercs).
You can use lifepath, or point-buy, but the goal here, is someone no army or merc unit would allow in their ranks, yet if they did, they'd have a war-winning asset based on skills and/or ability alone.
Please show your work, and explain why no army in their right (or wrong) mind will take this person.
