Awesome idea! Monastery type retreat. Young 'uns of all kind show up to learn basically everything, science, metallurgy, farming. In return, we get a well-educated middle class that also has weapons training. This is fucking awesome.
If Tymon isn't very approachable by himself, then we should go through Galen. Search out any knowledge about him, what he's like, who he's friends with, etc.
Once Galen gets back, we should use him to learn more about Tymon, and convert Galen first, if possible.
