Ah--ahaha, you're right. I hadn't even considered what could happen if this means we're able to travel between dimensions after we've saved Aellyn. You could have hundreds of different worlds you suddenly need to negotiate diplomatic relations with, and that's not even taking into account their politics.....

[The distress over imagining being forced to choose between those sides is short-lived, distracted as he is by the thought of negotiating politics on a so much grander scale. And of course, the ruins, too, are something considerably more familiar to him.]

I've explored some ruins too, while I was traveling in my world--though any treasures there were wasted on me, since I'm no scholar.
