Ok, so Perpetuals can die. but who will kill the Emperor and how? If no one will kill the Emperor before the Golden Throne will destroy itself, then the Emperor will simply disconnect himself from the Golden Throne and be revived automatically with his Perpetual effects(as we know that time has no effect on the Emperor).

The Avatars of Chaos Gods exist, that's no secret and they can enter the realspace whenever they want or can. It can be a daemonic invasion, a Daemon World, or a Daemonhost.

No need to go "fully" into the realspace, since their own presence is enough to change the situation.
