I'm going to be annoyed if we're somehow able to save the void and everyone in it. First, because I don't like the idea that somehow we're capable of doing something unsundered Ancients weren't able to do after 10k+ years. Second, because we just went through a whole spiel about how if an entity's aether is corrupted long enough that physical transformations take place there's no going back. Third, because much like the First I don't particularly get any satisfaction out of saving desolate worlds. We'd be restoring the 13th for who exactly? Cyella and Unukalhai? Why? What purpose does this ultimately serve?

I could get behind a merge of the First and the 13th, if that's possible. I just don't want to start a trend where it turns out every shard has fared really poorly and is on the brink of collapse where we're able to save one small pocket of remaining humanity because for gameplay reasons we'll never explore the whole shard. Especially if we develop inter-shard travel, we may as well just move survivors to the Source and start mitigating rejoinings. :P
