A charming yet clueless rogue. Actual criminals realise after knowing him for a bit that he seems quite sheltered, like a rich kid playing bad boy. In fact he is a rich boy—at least, richer than all the people he currently hangs out with—all the way from Salero far to the South.
 
Salero is the richest city in the world. Whatever Oswald's actual life there was like, he hasn't told anybody. When he first got to Malfa he used the alias Timothy, with a fake accent, but he's abandoned that at least with people he knows.
