I wouldn't use the NPC. I am assuming that Sir Aiden is part of the imperial Consigners and therefore searchable. That's the one I will be using.
Plus splitting comps between multiple, and unsearchable, consigners is part of what the problem we have right now.
A start to a solution is in place. I feel sorry for you who think that Sir Aiden is a poor idea. I think you are just arguing to argue at this point.
