He's carried fragmented memories of another life since childhood, though nothing concrete enough to fully understand where he came from. Rather than let that mystery define him, he grew up alongside his undead guardians and eventually swore an oath to Gracefeel, the deity they worship.
Once he came of age, William left the City of the Dead behind to see what the outside world actually looked like. His mission isn't complicated: help people who need it and rebuild faith in Gracefeel. He's described as someone willing to extend a hand to those in trouble, which tracks with the whole oath thing.
The Dragon Factor he carries is notable, though fans have noted it's never explained in overly convenient ways—it's just part of who he is.
