My castle. Back home, I had a castle capable of diving beneath and tunneling through the deserts of Figaro - large, featureless deserts. Finding one's bearing was difficult, and made only more difficult when the destination moved.

Doesn't quite seem practical for Mayfield, however. There's too much architecture, it would be noticed if it tried to move anywhere. If we could manage something else equally mobile, though? Barring that, we could take it underground, but you would have to find a location where there are none droned.
