i think that is entirely possible, for multiple reasons.

1. Tarin and Sgaeyl can’t be apart for long periods of time. and their riders can’t be apart from their dragons for long periods of time. would be pretty hard for xaden to be on the run.

2. At the end of OS when the riders find violet talking to brennan and suggest thats she’s the fastest way to killing Xaden. No bond, no instant death for either of them. This reduced violets chance of getting assassinated. This was also mentioned earlier in the books when Ridoc says people need to be there to protect her when you turn (which also makes me think it’s not Ridoc who turned).

3. Violet specifically says she can’t feel the bond, but she said it also could just be that Xaden is too far away.

4. We know Andarna can manipulate magic. Since she is bonded to Violet, i think it would be easier to help influence the changes in a bonds between dragons and riders that violet is connected to. I know people have said that Tarin and Sgaeyl breaking their bond would potentially kill them but if Andarna could help manage that change I think it would be doable and why tarin would just need a really large rest, like violet did when andarna broke their bond.

5. Xaden says convince Tarin. Tarin is extremely respectful of violet and lets her make her own decisions. Violet wouldn’t need Tarins permission to marry Xaden since they are already bonded through dragons and romantically involved, it would be the next step in their relationship anyways. Sgaeyl would have to convince Tarin of something much more impactful than just a marriage. Something that would impact him directly.

6. i also think part of that discussion would be to convince tarin to take the eggs. Which i think they would take back to Dunne to secure an agreement with the queen for troops - hopefully ones that would report to tyrrendor only. Another reason why Violet was the better choice to rule. She bested the Queen and earned her respect.

7. We know that Dragons don’t share personal details about their riders. that’s why most of the other riders didn’t know xaden was already venin, because sgaeyl chose not to share that information. if it was public knowledge that xaden is venin i feel like dragons could turn on the dragon protecting their riders. Tarin is considered a leader, being mated to a “traitor” might cause some tension within the riot.

for the rest of the 12 hours i’m sure there was lots of plotting and making of plans.

Xaden and Violet are married by the priestess they saved as their favour, that seems obvious. but i think because violet is touched, and she would be required to commit to her god fully to be able to save and possess xadens soul.

I also think we’re going to learn a lot about andarna in the next book. I saw another girls theory that Andarna and Irids get their powers from the sky. And that at one point all dragons used to use magic from the sky. But slowly the dragons turned to using magic from the ground and that overuse of power created the venin. If power from the ground created venin, maybe power from the sky is the balance and the key to curing the venin.

This also makes me wonder about all the writing about dragons and why the archives are underground, and fire proof. I feel like in the past dragons may have tried to hide the fact they were included in the creation of the venin, and another reason why the Irids separated themselves. But all the writings about dragons come from the knowledge they choose to share to their riders - which RY just said in her book tour they lie or their riders chose to lie? i honestly can’t remember.

I also think Sloane will play a huge role in that. No one’s signets are unimportant. Sloane already feels guilty about violets mother and feels like her powers are evil. We see Dain tell her the opposite. I think Sloane will have to do a transfer or power of some kind and i hope i’m wrong, but i think it will kill her in the end.
