Magic is being reawakened in Dragonslayer, and not surprisingly, a dragon is too. Naturally the dragon isn't too thrilled with the state of the world occupied by humans and quickly decides to rectify it. This leaves the Bishop, who's secretly teaching the magic, to summon the one person left who could have the skills to slay the dragon. Except he's drunk. And overweight. And not too particularly inclined to follow anyone's orders... let alone the Bishop's.
