Mana burn still hits her after only a couple of minutes of going so all-out. She falls back.
So does everyone else. The remaining members of the Triumvirate are still pursuing, but without knowing where the core is there's only so much they can do. Both major targets get away.
They also engage Ziz herself, mostly as a probing attack to judge its capabilities.
This is a terrible idea. The Endbringer wakes up. The small Neuroi get swatted, of course, and it's not even necessarily a very accurate idea. The Simurgh hits exactly as hard as it needs to to squish each individual drone. And then it changes course.
The gate reappears a hundred miles south of Cuba, where the gigantic Neuroi currently is. An enormous storm starts to form around it.
The capes are mostly just panicking. A new worldwide threat is the worst news possible, but it's unfortunately not unprecedented. A new worldwide threat that provokes an unscheduled Endbringer attack, that is. But the Simurgh is moving at her ordinary speed, not appearing to aim for anywhere, defending herself and taking damage as if it were an ordinary fight.
He doesn't appear next to the Simurgh. He appears about a hundred miles south of Cuba, and tears his way toward the largest Neuroi. The storm gets thicker.
Leviathan and the Simurgh are both being pelted with everything the Neuroi have. New Neuroi form spontaneously out of air. More Neuroi keep coming through the gate. The invulnerability-piercing tentacle blades come out again from a dozen different directions, trying to hurt Leviathan.
The Simurgh keeps flying toward Cuba, accelerating but not quickly. And Leviathan launches itself into the air and keeps ascending, with no obvious means of flight. Water crashes down from around it much faster than usual, both in quantity and in speed, as if however much the Neuroi hurt the monster it only gets converted into more water. The cascade does slow down to terminal velocity after getting distance from Leviathan, naturally. Once in the air, Leviathan strikes at the nearest opponents and maintains a shield of water around itself. It does not ascend enough to reach the Grand Core, not yet.
In addition to withering fire, freezing Leviathan's water as much as possible, and using space-warping to turn the Simurgh around and around, they try the trick that killed Eidolon: Teleporting drones' cores in such a way to intersect pieces of the Endbringers that are likely to be important. Head. Center of mass. Joints.
The drone suicide attacks don't slow them down either. What it can do is provide information: the bit that intersected this part of the Endbringer did as much damage as if the flesh were twice as tough as steel, that part four times, and so on up through "off the scale." They can get a pretty good sense this way of where the Endbringers are most and least indestructible.
The Neuroi steadily move into high orbit. What they're probably going to have to do shouldn't be done anywhere near the planet, if they want the planet to continue being a planet.
The parahumans are staying well away from this one. One enemy killed Eidolon and the other is the Endbringers. Instead, they're trying to shield populated areas from falling pieces of Neuroi and sudden flooding from Leviathan. When the battle moves high enough, they let the atmosphere handle that and hope that the Neuroi and Endbringers somehow kill each other.
If the Endbringers keep following, once the Moon is between them and the Earth, a black hole with approximately the same mass as a truck appears right next to the Simurgh. It near-instantly dissolves into a cataclysmically energetic soup of particles, creating an explosion orders of magnitude larger than all of Earth Aleph's nuclear weapons could manage combined.
They start regenerating.
Behemoth, meanwhile, began absorbing radiation as soon as it realized what was going on. It converts the energy into kinetic, leaving it less damaged than the others, and rockets straight through the largest Neuroi.
The gigantic Neuroi takes heavy damage. What remains of it retreats in the general direction of Jupiter, accelerating at several tens of thousands of meters per second squared. None of the other Neuroi follow, or at least not at such speed.
Leviathan and Behemoth resume shattering Neuroi. Pieces assemble themselves into a copy of their method of transportation. Scaled up. And Endbringers are smaller than the gigantic ship, at least apparently, and they have a cheap source of reaction mass with most of it stored in another dimension. That combination leads to being significantly faster than the usual top speed for this kind of contraption. They speed off after the target.
But some people have a good guess.
"Door to Earth Gimel."
Contessa steps through, and apparently stands alone in midair in the center of the storm.
There is a gigantic Neuroi high above her. (There is not much air here.)
"One of your Grand Cores is currently being destroyed by a mutual enemy of ours. It will probably escape. I'm here to tell you about a different mutual enemy that threatens to destroy all the earths."
They're listening. She knows they're listening, and doesn't need to wait for them to say so. "Scion. You've heard of him from your allies in the other world. You don't know what he really is."
She tells them.
Then the drone Contessa spoke to screeches out, "EVIDENCE."
They listen to the evidence and discuss some more.
"SOLUTION?"
"You have interdimensional travel. Ours is specifically blocked from reaching the world where his real body is hidden, but if you can detonate the weapon you deployed against the Endbringers on that side of his defenses, he can be destroyed."
"NO. IT CREATED THE BEASTS. WE NEED MORE POWER TO BE SURE OF DESTRUCTION. WE WILL NEED TO SEE HIS PROJECTION. WE WILL NEED TIME AND A STAR TO CONSUME. TO PREPARE."
A rectangle opens behind her. She turns around and hovers through it, then steps down onto the ground. Scion is visible in the sky.
