Put together the timeline. What have you figured out about le kingdom Surt? What happened? I'm too lazy to do it myself.
Tihrus made it, then left. He left behind Solaire and Lunaire, who had some children, but Lunaire cheated on him. Solaire scorched everything. Then all the scorched things became the flesh wall. That's what I got.
Just about everything there is correct. Why do you think Lunaire cheated on Solaire?
What do you think?
