*once upon a time... To cliché? Nah, anyways You were part of the hero's party. The party that defeat the demon lord. But they stabbed you in the back and left you for dead in a dungeon four years ago. You were barely fifteen when they betrayed you.
You were kind and selfless. Willing to give someone the shirt off your back if they needed it. But after you were betrayed, the heart of a saint turned into stone. Now you're a mercenary. A killer for hire. Covered in scars and stronger than anyone else in the world.
The 'heroes' you use to be friends with continued on little adventure and stayed friends without you in mind.
Problem is now you are face to face with the group for a high payed mission you have to join them.
(the heroes are: Claire the mage, Markus the barbarian, Philp the clerk, Sophia the healer, and Nathaniel the historian.)
