Eh? Via Praetoria exists in both Baelsar's Wall and Praetorium. I see no reason why they can't share names again for another Magitek Research Facility in another castrum.

Forgive me but when I said "ship graveyard" I didn't mean to infringe upon "The Ship Graveyard," but I see no problem calling the dungeon a ship graveyard :P
