We roll into our final destination, Devil's Castle, breaching from the SW wall. It's quiet, but we're on alert. This is a huge, attention-attracting landmark, and the interior is treacherously cramped. A nervous player could be lurking in the tower, in the gatehouse, or in another nook. We make a revision to our rules of engagement: shoot first, don't think, kill anything .
Everyone heads up to the tower, I stay downstairs to keep an eye on the entrances. A few moments pass while they circle up the stairs, then I hear: “Get up here. Get up here. Holy shit.”
