I'm aware of the origin of Gaelicats - I was referencing the joke on the Triple Triad card about them being Voidsent.

With that said, the trend lately has been for any impossibility to somehow suddenly have a solution so I'm not willing to write off the inhabitants of the Thirteenth as being 'unsalvageable' just yet. Some will no doubt be too far gone but there's a lot we don't know about the place and it's likely that there's pockets of survivors who have managed to hold out/find an alternative solution to their craving for aether.

It'd also be a good way to have various side stories merge in a grand conclusion since there's a few individuals on the First seeking a way to restore the Thirteenth.
