There are certain mysteries like the missing Primarchs, the Rangdan Xenocides, Subject #696, the Halo Stars or Ghoul Stars that are good enough as they are

But there must be one that you think it could use some more info, maybe the Dark Cells, the Deep Warp, the Veiled Regions etc...

If done well though, we dont want another Terminus Decree fiasco

If for some reason, Guilliman, Ghazghkull, Vect, The Silent King, The Ethereals and Abaddon disappeared out of thin ain.

I would say the Drukhari, but then again Vect probably has some dozen back up plans

That one Daemon of Tzeentch felt fear for the first time when he see the little guy

What about other warp-y and anti warp-y beings

The rifle is supposed to desrrot the nerves and neurons, but rubrics dont have any do they

During the Plague Wars Ku'gath had this sideplot making the disease, added the blood of Guilliman and it was said to be potent enough to kill a Primarch

Blah blah blah Mortarion fights Guilliman and injects him with it. On the brink of death the Emperor saves the Avenging Son and sets Nurgle's garden on fire

Now, is there any Godblight left, or was all of it injected to Guilliman ? Is there any more blood so that Ku'gath could make some more ?

Most accounts of the war recall endless hordes of lesser daemons, some separate daemonic entities like Drach'nyen and many traitor space marines sent by Lorgar

I cant recall any mention of Bloodthirsters, Keepers of Secrets or Changers of Ways
