After checking this place out....this could potentially be the largest home on the server. The fortress to the east could be bridged as well. Wasn't Mindless looking for this setup? Bridged fortress/fortress/tower?!? Insanity!!!
A bridge must involve a tower at each connection; you can't bridge a fort to a fort, or a keep to a keep. In order to do what you're thinking, you'd need to have it set up as Fortress-Tower-Fortress. So one would need to buy the tower behind this tower for sale, and then it could be done.
Didn't know this Dal. Seems like something that should be addressed. If one can bridge two towers, why not keeps, castles, and fortresses?
