So... this may fuel a LOT of speculation about events to come. After seeing this, I felt it appropriate to bring it here to the Lore forum. I'm going to hide the image link to try to prevent any unfortunate spoilers. Also, keep in mind there is no telling how this encounter may play out. It's completely out of context, but it's pretty clear who the parties involved are. Click the spoiler and continue on in this thread at your own risk.
I think it's safe to assume the Dragoon on the left is Estinien, the center is Derplander, then one of the twins and of course Iceheart. I can only imagine what is meant to happen here. Part of me deeply hopes that this means instead of just reuniting with the Scions, we instead are forced to take matters into our own hands. I suspect that Hydaelyn has passed off guardianship over us to Midgardsormr... who is clearly interested in seeing us accomplish things on our own merits. Won't it be interesting if these wind up being some of our new allies?
