This is an easy one for me to answer, since the climax of both Thurion's and @[member="Thyrian Ashborn"]'s story arcs involves the two meeting. While the details aren't planned out, since this won't happen for a long time, they'll eventually reconcile and go their separate ways, at peace with one another. Sad as it might be, they've outgrown eachother and both have lives the other doesn't have a place in. Just knowing the other is alive and well will be enough for both of them. Thurion has his family consisting of @[member="Kida Ravos"] and @[member="Nina Vi'dreya"], and Thyrian will forever serve his beloved @[member="Kära Vi'dreya"] in whatever endeavour. They're at separate sides of the spectrum, but they share many traits such as the over-protective nature and honesty.
