Definitely an Orthanc assignment is the Earthquake the night before last! It was cool and kind of exciting, but of course is not really a 'nice' thing for The Shire
It was a bit spooky being waken by the bed violently shaking about and smashing my head on it, and hearing the cats run away in sheer terror, but it was also fascinating next day! The sound was the oddest thing, like a roaring noise and a crashing! And I dismissed it as just a night terror!
