Magnus destroyed a titan, not the Emperor.
Yea...and the Emperor's [i]gaze[i] made Magnus, a titan killer, locked to his seat unable to do anything.
The Emperor was only a necessary part of the Golden Throne after Magnus broke it (incidently, but punching right through the Emperor's psychic defenses. Magnus also had prescient knowledge of Horus' betrayal and the Emperor was blind to it (along with Eldrad and his crew). There's a case that the Emperor wasn't even as good a psyker as Magnus in those two things).
Magnus had knowledge because the Daemon told him,
IIRC. To show Magnus that the best of them had fallen. Daemons hate the Emperor, why would they tell him? As to Magnus punching through the Emperor's defense, it took all his own power, all his Legion's psykers, AND thousands of sacrifices to try to get to the Emperor.
The Emperor was able to make people he genetically tailored for, and ritualistically indoctrinated, for unswerving loyalty to himself kneel in a non-confrontational situation. In direct combat, he was nearly strangled to death by an ork. He couldn't even make one ork kneel, let alone blow that ork's army into smithereens.
Just those he genetically tailored? How about normal human beings going insane by just looking at him. Or going blind. Or the xenos mentioned by Kharn in the World Eaters short story being completely annihilated by the Emperor's power when Perturabo could not beat them. As to the Ork, the the Ork was described as a very large and powerful Warboss, and also Horus says that they saved each other numerous times in the early Crusade. And myself or ChrisWWII said anything about the Emperor destroying armies. Our argument stems from you saying he is no more powerful than an Eldar Farseer, which is, quite frankly, ignorant.
There is simply one single event in which the Emperor was able to use his psychic powers offensively at the level you're describing, and that last act cost him his life.
.....After he took it easy on Horus to try and save him. After Horus obliterated the Marine that stepped into the chamber, the Emperor used his power....to chase off ALL OF THE CHAOS GODS AND OBLITERATE HORUS'S SOUL FROM EXISTENCE.
His not being killed by the Emperor from across the galaxy after he became a traitor is exactly the evidence to which I refer.
The Emperor didn't want to kill him from across the galaxy. He wanted Russ to bring him back in chains. Horus manipulated Russ into burning Prospero.
He also didn't want to destroy Horus because he thought he could save him. That's why the Emperor told the Assassin temples to stop trying to assassinate Horus.
If you can find even one case of the Emperor using his psychic powers on an army-wide destructive level, feel free to PM me. Otherwise I'm checking out of the thread as it's devolved to the point of propaganda.
Myself or ChrisWWII have made a claim of him destroying armies. Only that he is vastly more powerful than Magnus or Eldrad. Eldrad didn't know Fulgrim was corrupt until he saw him face to face and saw Fulgrim's daemon sword.
Go ahead and leave the thread. That's typical of people on the internet who have nothing to back up their claims. Next time you want to debate something, bring some evidence. Or a decent argument.
