I am a Mercenary.
Great strength that stands alone. You're strong enough in solving problems that you'd loan your skills out -- for a price. To be a Mercenary isn't necessarily to be a literal Soldier of Fortune, but it does mean that you have great practical knowledge of the world, and great ambition. And by applying both, you will climb the ladder of Renown to great personal triumph and glory.
Yep, that's me to the tee. Ambition coupled with knowledge and talent... and serving loyally while I am getting what I expect - but first and last I serve my own interests.
