Hmm, well I guess...

Go to Forgotten Springs for obvious reasons and live happily for the rest of my days.
Study Allagan technology and history; collect it, too - and explore Allagan ruins.
Distance myself from the Scion idiots, except Y'shtola, Krile and Urianger.
Refurbish Dun Scaith into the perfect Victorian-esque location it seems it would've been; then open it for people to live and so on - oh, and make it illegal for Lala's to be there.
