Thinking about having the Grineer mobilize a force to head toward the event. Might need a small timeskip of a day or two in order for that to be possible, though.

Well, there is the problem with Daleks being very aggressive towards anything that isn't Dalek, and I'd need someone's consent before making them open the Ark 'cause they'd come out swinging. However, I also mentioned change for the Daleks may come. They may not be the same in a few months, having to reflect upon their own existence in solitude.
So I guess they'll build up for now. I'll leave this here though, cause it's epic.
Part of me wants to add the Corpus, or even the Infested. I just don't think we need another mindless group whose goal amounts to nothing more than spreading themselves via the annihilation of all that exists.
