Princess Celestia: We were so blind...so foolish...we were so busy paying attention to one prophecy, that we completely forgot about another...



Twilight Sparkle: What do you mean?



Princess Celestia: The time has come...the time every Terrordex has dreaded since the Almighty One drew his first breath...Onslaught has arrived.



Twilight Sparkle: Onslaught?



Princess Celestia: Long ago, when my mentor and surrogate mother, Lady Amalthea, was still a child, a prophecy was made by Michael Demiurgos...that an Hyperforce Overlander would be slain by one of his kind, and then reborn as an Obscurial. This was Onslaught, and he would make entire civilization scrumble into dust...the poem....



Twilight Sparkle: Poem?



Princess Celestia: "Pretenders sit upon my throne.



I remember my death.



The world is at zero, six, seven.



The Babylonians knew the truth.



I am looking over your shoulder.



Continue to wait for my ascent."



A coded message, passed from generation to generation...a warning about the coming of Onslaught...



Twilight Sparkle:...Linkara is Onslaught.



Princess Celestia: I'm afraid a new menace looms over the entire Multiverse...



Twilight Sparkle: There's gotta be a way to fight it! There was another Obscurial...Credence Barebone...he was defeated somehow! Do you remember how?



Princess Celestia: I'm afraid not. No one does. Obscurials may not be Hyperforce Overlanders, but they are still as above us as ants are above Ponies or humans. The Killing Curse can't kill an Obscurial. Tachyon cobalt can't kill an Obscurial. The Falcon Sword can't kill an Obscurial. A beam of pure Quintessence can only mildly annoy it. It does not know pity, or remorse, or fear, and it will not stop, ever, until whatever it targets is dead.
