"I've already asked for that," Estre says, annoyed. "They won't even consider it. Even if Cinza were banished to land, the whales still consider her a threat, cavorting around with humans. What if she were discovered? What if she decided to return one day and finish the job of destroying the Eternity Orb? I think their real fear is that other merfolk might be inspired by what she did. That banishment might not seem that bad, or even preferable, if they try to act out themselves." He scoffs. "Even banishment is a privilege, and they don't want to give that privilege to a traitor."
