Raven

Raven was Phantom's mentor before his death. Not much is known about Raven aside from a few quests from Phantom's storyline. He taught Phantom "Learn a skill once, and you'll forget it next Tuesday, but learn a skill twice and you'll master it for a lifetime", which Phantom recalled when advancing to his 2nd Job. However, apparently, Raven did not follow his own advice and learn how to disarm a bomb more than once, which ultimately led to his demise. Phantom and the rest were all very sad, but this did not deter him and he would become the greatest thief who ever lived, and Phantom hopes the "crazy old coot" would be proud of him and jokingly says he's glad his master is dead or else he would have robbed him.
