[Hermes]

Well, in titan Quest, you play this hero/group of heroes(If you play multiplayer) Who come to this small town, and you end up having to kill this monster for them. Well, a bunch of things lead you to Medusa's lair, and you end up getting enlightened to the fact that the Telkine have come back, and have begun to let Typhon, enemy of the gods, loose. You go through the Greek, Egyptian, and Chinese mythologies, coming to know of all the gods from these lands, then end up in Babylon, then you go to Olympus, etc.
