[@Kho] It was nothing, some stuff said made me think of it as a whip of fire moment for a second. But I was wrong.

Naah, no fire whips for poor Sin xP
It was more to get him out of there after the Astarte events ('cause all the Vestecs of the world will be after him) and also to bring Amestria back a notch and let everyone else catch up technologically before he returns and starts building up again
Also to introduce the Vowzra's Victors more solidly and further expand on Bard's role on Chronos and relationship with the Victors. It's also feels kinda nice to have Sin locked up in the Cube :)
