Superworms: Common Ground, Part 1

My name is Sir Gregory Linham and I am a Superworm. Best of four Superworms, I'll have you know. And I will be dead in a matter of days - if not hours. If I had the chance for one last mission, I would use it to stop my brother from coming after me. But I won't get that chance. So he will come. And it is the only glimmer of hope I have left.
