[ooc: I wasn't prepared for Jack's sudden possessiveness about "his" new toy.

I didn't catch that you were setting up conflict between Arthur and John until after your Last post.]
Arthur quickly does another life detection spell, slightly altered to make it look like it was cast from the castle. Signs of life are shown, with the usualy delay, a few hundred yards inside the cave. A detect magic spell, however, does not detect anything.
Arthur "That's odd. It's the same thing I encountered on the way to the manor. There seems to be some sort of selective filter which allows some spells to pass and blocks others. I don't know if it blocks on the inward path or the return path, though, or how it would affect spells cast inside it. It's almost like a semi-permeable membrane."
Everyone takes a moment to check themselves over and make any Last-minute preparations for whatever they will find.
