Chapter 2: "Eyes in the Sky
The golden portal over the Sanctum Sanctorum lasted four minutes and twelve seconds before it closed.
That was more than enough time for three separate satellites to flag it, one very irritated night-shift analyst at a nondescript building in Brooklyn to spill her coffee, and a phone call to go out that started with the words *"Sir, we have an unidentified energy signature over Manhattan, and it's not one of Strange's."*
By the time the call reached Maria Hill's desk, the portal was gone. What wasn't gone was the residue — a faint gold shimmer clinging to the air above 177A Bleecker Street that regular cameras couldn't see, but that a certain kind of sensor could.
"Get me eyes on the ground," Hill said. "Not agents. Eyes. I want to know what walked out of that thing before we knock on Strange's door and get magic'd into next Tuesday."

Inside the Sanctum, Stephen Strange was doing the mental equivalent of trying to read a book with half its pages missing.
"So let me make sure I have this," he said, pacing a slow circle around the golden lattice-map still hanging in the air. "Somewhere along the seam between my reality and yours, something is *eating* the boundary. You don't know what it is. You don't know who's doing it. You don't know why here, why now, or why your side even *has* a seam with mine to begin with, since as far as I'm aware, this isn't a thing that happens."
*"Your awareness,"* Nabu's voice said, dry as a dead riverbed, *"is bounded by whatever your teachers taught you. Mine is bounded by three thousand years and the memory of every sorcerer I have worn like a coat. I am telling you it is not a thing that happens either. Which is precisely the problem."*
Wong, who had been silently cross-referencing three different books simultaneously with the ease of a man riffling through a mental card catalog, finally spoke. "There's precedent. Thin, but it's there." He turned one of the books around — old vellum pages, illustrations of concentric circles, one bleeding into the other. "Kamar-Taj records reference something called a *convergence fracture.* Two realities pressed close enough, for long enough, that the barrier between them thins. It's not supposed to *tear*, though. Not on its own."
"So something helped it along," Strange said.
*"Someone,"* Fate corrected. *"Boundaries this old do not fray from neglect. They are cut. I felt the wound the moment it opened, which means it is recent — days, perhaps hours, on my side of it."*
Strange's sling ring hand twitched, an old habit. "Then we need to know what it looks like from this side. If someone's cutting from your universe into mine, there should be a matching wound *here.*"
*"There is,"* Fate said, and the lattice map shifted, gold threads sliding aside to reveal a second point of rot — smaller, fresher, pulsing faintly, its location resolving into a set of coordinates that made Wong go very still.
"That's not a coordinate," Wong said slowly. "That's a building."
Strange leaned in. "Which building?"
"Stark Industries R&D. Sub-basement level, restricted wing." Wong closed the book. "The one that got 'decommissioned' after the Ultron incident and was never, as far as anyone's paperwork says, reopened."

The knock on the Sanctum door came exactly six minutes later — three sharp raps, followed by a voice that had the particular flatness of someone who'd had this exact conversation with a wizard before and hated it every time.
"Strange. It's Hill. Open up, or I start assuming the golden light show over your house was hostile."
Strange opened the door himself, Fate's presence a golden shimmer at his shoulder that made Hill's hand twitch toward her sidearm on pure reflex before her training caught up with her eyes.
"That's not hostile," Strange said. "That's — complicated. Maria Hill, meet Doctor Fate. He's not from around here. Literally."
Hill's gaze swept over the ankh-crowned helmet, the crackling gold aura, and did not blink. Fury had trained his people better than that. "Another universe."
*"Another universe,"* Fate confirmed. *"Currently bleeding into yours through a wound someone appears to have carved into a Stark Industries sub-basement."*
There was a pause that carried the specific weight of a woman doing rapid math on how many forms this was going to require.
"Of course it is," Hill said. "Get in the car. Both of you. I want this contained before it makes the six o'clock news, and I want to know how deep this goes before Fury finds out from a satellite instead of from me."

The sub-basement smelled like ozone and old copper.
Fate's presence washed the corridor gold as he walked it, Nabu's ancient senses reading the walls like text. Strange kept pace beside him, sling ring humming low, while Hill and two agents held the rear with weapons that both of them privately suspected would do exactly nothing if things went sideways.
*"Here,"* Fate said, stopping at a section of wall that looked, to human eyes, like plain reinforced concrete. To Fate's sight it was anything but — a scar of black light running floor to ceiling, humming with a frequency that made Strange's molars ache just standing near it.
"That's not natural," Strange said. "That's not even *unnatural* the way most of what I deal with is unnatural. That's — surgical."
*"Someone opened a door here on purpose,"* Fate said, *"and left it propped. Not to let something in. To let something out — slowly, so no one would notice the draft until the room was already cold."*
Hill's radio crackled. She held up a hand for quiet, listened, and her expression didn't change — which, Strange was learning, was how you could tell it was bad.
"We've got a match," Hill said. "Security footage, three nights ago, restricted access log. Someone came down here who wasn't supposed to have clearance anymore." She turned the tablet around so both sorcerers could see the grainy still frame: a figure in a lab coat, face turned just enough from the camera to blur, one hand pressed flat against the wall exactly where the black scar now pulsed.
"Recognize them?" Strange asked.
Hill's jaw tightened. "Yeah," she said. "That's a problem."
*"Then so is what comes next,"* Nabu murmured, and behind the black scar in the wall, something on the other side pressed back.
