The new codex for the Grey Knights is out, and it tells the Terminus Decree. I read about this right before the License to Buy a Pizza thread, so all I could see was Orks. Apparently the decree says that if the Emperor stands up from his throne, is reincarnated, or ascends to godhood, the grey knights must stop this. There's hints that the emperor is already reborn against his will, and doesn't even know what or who he is yet. So a new story is building up.
I haven't found any news about it, only YouTubers and random reddit threads. This is coming at the same time that Space Marines are no longer male.
I guess I should mention this is WarHammer 40k stuff.
My bet is the introduction of a new god pantheon: The “Order Gods” or some shit. God Emperor, the Omnissiah, a new Eldaar god, and a Tau god.
You may not be wrong. We have already seen a new Eldar God of Death and Rebirth awaken in the form of Ynnead (even if they fumbled that plotline), and there was already an physical manifestation of The Greater Good that showed up in a more recent Tau book.
Also, point of order, it would be the Machine God. Big E is the Omnissiah (think of it as the difference between God and Jesus).
Isn't the Machine God just one of the Necron C'tan, specifically The Dragon buried on Mars?
Yes, but the Mechanicus doesnt know that or know that Big E was the one who defeated it and sealed it back away. They just know that The Emperor seems to know everything about how their technology works even without having studied it (he had, but they didnt know that), so they assumed he was a prophet of the Machine God, which is why they followed him.
And there is some implication this was all part of his plan.
Is The Dragon still intact? I remember reading GW nerfed the C'tan so that any time one showed up on the battlefield it was only a shard/sliver of its true power because having a fully manifested entity that naturally drinks stars running around wearing necrodermis was maybe a bit much in terms of power.
