A difficult choice. Rudeus's primary family is now the one he established, not anymore the one he was born in. While one might say Sylphie and the yet-to-be-born child ought to be safe in that academy city, who can really say? The larger story began with with an entire important city getting wiped off from the world. Assuming he made the trip the normal way, his kid could already be over two years old by the time he's back, assuming everything went smoothly. That would be rather cruel considering Rudeus never even got the chance two witness his sisters grow up. But then again, it's a cruel world. If Zenith could be saved with his help, and he didn't go, things would never be the same ever again.

All in all, Norn better look after Sylphie and not bother her by arguing with Aisha, no matter how much Aisha provoked her.
