As of the latest chapter (Chapter 72) we find out from the recorded message left by Minerva (James Ratley) about the three options that the escapees can choose from. Escaping with the kids safely to the Human World. Breaking the promise and creating another all out war just like the times before the promise, a 1000 years ago. Looking for the Seven Walls The only other time this has been mentioned before was the farewell with Musica where she gave a pendant to Emma and talks about there being "another promise". Obviously there's still a lot to be said about this as we know close to nothing about the seven walls but I thought it'd be interesting to hear your thoughts on what you think the third option besides rebelling or escaping could be? What do you think is the Seven Walls? What is this other promise than Musica mentioned after parting ways with the kids? What's the pendant for?
