You still had to work to go to his thrones realm. Savvy still attached an entrance to her ship. He wanted to have dominion over everything, so him attaching his throne was his step into the claim. His entire being was the goal of nothing can exist without his will upon it, it's also why his xivu felt if he looked away you could possibly cease to exist (observer, Schrodinger's cat). So that would have served his purpose and needed to be done. His realm is everything outside. It's why Toland was losing his mind when we killed him. I mean you killed the being that laid claim to our universe, his throne was everything. Maybe Toland bought into the belief that the king was actually attached to everything. That being said, let's say the Warmind has the entire universe within it's purview (the anomaly) and it detected an axion discharge from it. It's error code is imminent end of the universe, but to an AI that has superluminal thought, imminent could actually be a long time. So, perhaps everything that's happening, the end within another end, all stems from: the black heart of the garden, crotas death (which led to), oryx death...so there is an element of destiny there, if you hadn't done one of the several ends, would things have stopped. If we stopped trying to make prophecy become reality would things be different. I mean I looked at the grimoire of the nine as a prophecy too, so we are hitting all the marks for several different ones.
