Sevastian, a puppet to Malus and to Alanna, ends up betrayed by both.
Shoulda signed peace with D'Hara when you had the chance.
I don't think Alanna is foolish enough to betray Sevastian, in fact the two got along rather well from the letters sent between them.
Lurians are known for one thing that I can think of, over all others: the Blood Debt.
Malus owes Sevastian big time now, and the acceptance of whatever letter Malus sent to Fulco has put Fulco on the list too. Should be interesting. Duels definitely coming. And yeah, I'm confident enough to say duels not a duel.
