Becoming the Crisis - what are the consequences?

[Premu]

After a long break I started a new game in Stellaris as fanatical purifier. "Becoming the Crisis" looked like a perfect pick for this purpose, and I already escalted my threat level close to the final one.

Now shortly after 2400 after I've already killed one of the fallen empires, two others have woken up and just started the war in heavens. I didn't join any side, of course.

Now I wonder what will happen if I trigger the last threat level - will that mean that I'm automatically in a war with everyone else for the rest of the game? While I'm significantly stronger than any normal empire, the awakened empires are an actual threat to me. On the other hand, they will not be able to concentrate on me if they are also waging war against each other, or so I hope...

Also, I can apparently start a special construction once I've reached the last step - what will it do, will it be a massive strength boost for me in my task to clean the galaxy from xeno scum?

Only members of the galactic community will instantly declare war on you.

I'd still deal with the fallen empires first but its your game

OK, thanks - I now took the final step, and for now I'm in war with the completely overwhelemed neutrals which don't stand a chance against me.

The Awakened empires grow fast, though - especially the xenophile one. I don't want to attack them until the Sentry Spire is complete, though - I need to know where their fleets are coming to engage them at my terms. I probably will declare war on the Xenophiles first to make sure that they don't win too fast against the Xenophobes. And should they be gone I should be able to handle the last empire as well.
