What's changed:
1. Humans are no longer tithed (for now),
2. Werewolves are free of Vampyre dominion (for now),
3. Newly turned Vampyres are eager to take the potion to sate their hunger,
4. Once-Human Vampyres can cross the Salve to change back to Humans,
5. There is seemingly no effect on Trueborn Vampyres crossing the Salve
6. Safalaan and Vanescula lead Morytania together, though Vanescula is still probably the ruler. Efaritay is only an advisor. Safalaan's role is not explicitly made apparent.
("This is where conspiracy theories start, but Vanescula crossed the threshold herself towards the end and then..."
BUT
1. Humans are citizens of Meiyerditch, they are still poor, they are still an underclass though no longer mistreated,
2. There's nothing stopping some good old retribution against the Werewolves and enslaving those who do no cross the Salve into the West,
3. Trueborns are not happy with this situation (Vanescula says "Our new alliance is a difficult concept for them to grasp ... the notion that vampyrism is a disease is offensive to us ... I have as much control over them as I do over you).
4. The real power lies with the Trueborns? ("So long as I keep the trueborns happy"
5. The peace is tenuous (the first sign of anyone trying to take advantage of this ... to wipe out my kind ... this will all fall apart)
6. Misthalin has blisterwood ... Maybe?
Roald says: "Aeonsig is offering to aid the citizens of Meiyerditch in exchange for shipments of blisterwood".
But, Efaritay, Vanescula, Safalaan and even Aeons*g don't mention it. There's no indication of blisterwood harvesting. Is that sort of scale of blisterwood harvesting even feasible? Why would Vanescula agree to that? The trueborns certainly wouldn't, and they'd break the truce. Possible that Aeons** lied to Road?
He did say he will do his best "if for no other reason to get back into the King’s good graces."
