Hermes has stolen back the soul of someone he considered his friend. There were very few people who seemed to fit that description so this was something he had to do. Being the god of thieves meant that it was a simple task to steal something even as heavily guarded as a soul and having acess to the underworld makes it too easy. However, this isn't the first time he's stolen something from Thanatos, god of death, but it will be the last, if Than has anything to do with it. He's decided that it's time for Hermes to pay for all the trouble he caused. How will things change when he realizes that Hermes isn't just some irresponsible god, instead he's everything that he's needed.
