If the game was willing to bend over backwards in order to save the Tempered - who were, not so long ago, written off as 'unsalvageable' - then I imagine that it's plausible for an attempt to be made to reach out to the Voidsent.

We've also already seen examples of 'friendly' Voidsent in the form of the Reaper avatar and if there's any truth to the theory that Gaelicats are Voidsent? Well, that's more than enough reason to move heaven and earth in order to save the Thirteenth!
