The transition node hummed once, then spat Daniel Voss and Vannia Reyes out into Level 4 like discarded code. The air changed instantly — cooler, drier, carrying the faint metallic tang of old machinery and distant rain. They stood in a vast, abandoned warehouse complex: endless rows of rusted shipping containers stacked three high, overhead catwalks dripping condensation, and pale blue emergency lights that buzzed like dying insects.

Daniel rolled his shoulder, testing the returned strength of Immune All and Pestilence Type 3. The violet-black vein across his arm pulsed steadily, calm for the first time in hours. Vannia stood beside him, knife sheathed, silver shimmer around her hands dim but present. Her eyes were still red from the chamber, but her posture was locked — professional, guarded.
They had walked less than four hundred meters when the interface pinged.
```
[Proximity Alert]
M.E.G.-Style Outpost Detected (Modified)
System User Signature Inside
Designation Match: Blood Relative to Chosen-0008
```
Vannia's head snapped up. "Blood relative?"
Before Daniel could answer, a reinforced blast door at the end of the container row slid open with a hydraulic hiss. Warm yellow light spilled out. Three armed figures stepped forward — standard M.E.G. gear mixed with scavenged Backrooms plating — but the one in the center lowered her rifle immediately.
She was younger than Vannia by perhaps three years. Same dark hair, same sharp jawline, same economical way of moving. A thin scar crossed her left eyebrow. Her eyes — identical to Vannia's — widened in pure shock.
"Vannia…?"
Vannia froze mid-step. The knife slipped from her fingers and clattered on the concrete.
"Mia?"
The two sisters stared at each other across ten meters of damp warehouse floor.
Mia Reyes — interface scan confirming:
```

System Variant: Survival System v.17.4 (recently upgraded)
Active Passives: Precognitive Flare (Level 3), Kinetic Redirection (Level 2)

```
— broke into a run. She slammed into Vannia so hard both of them nearly fell. Arms locked around each other, Mia's rifle clanging against her back as she buried her face in her sister's shoulder.
"You're alive," Mia whispered, voice cracking. "I saw the outpost logs go dark… Partygoer signatures everywhere… I thought the whole family was gone."
Vannia's arms tightened around her. For the first time since the revival, she let the tears fall openly.
"They are," she said, voice raw. "Mom and Dad… Partygoer 0 showed us. He erased the entire outpost. Everyone."
Mia pulled back just enough to look at her sister's face, then over at Daniel. Her eyes flicked to the glowing vein on his arm, the pipe resting across his shoulder, and the golden edge of the Chosen interface visible in both their eyes.
"You're the one," she said to Daniel, not a question. "Chosen-0007. The one who ended the progenitor."
Daniel gave a single nod. "Partygoer 0 is gone. Level 3 invasion terminated."
Mia exhaled shakily, still holding Vannia's hand like she might vanish. "I felt it. My Precognitive Flare lit up like a flare gun the moment he fell. I knew something massive had shifted. I just didn't know it was my sister standing at the center of it."
She gestured behind her toward the lit outpost entrance.
"We've got twenty-three survivors here — mostly M.E.G. remnants and a few independent system users. We've been fortifying this warehouse cluster for weeks. Stable almond water, working terminals, even a partial map of Level 4 exits. But the Pantheon's been whispering about two new Chosen signatures moving through the levels…"
Mia's gaze returned to Vannia, then Daniel.
"I never expected one of them to be you."
Vannia wiped her face with her sleeve, but didn't let go of her sister's hand.
"Neither did I."
Daniel stepped forward, pipe lowered but ready.
"Chosen-0009," he said quietly. "The system is accelerating. Three of us in one place is not coincidence."
Mia offered a small, tired smile that looked painfully like Vannia's.
"No. It isn't."
She jerked her head toward the open blast door.
"Come inside. You both look like you just walked out of hell. We have coffee — real coffee — and I want to hear how my big sister became one of the Pantheon's chosen killers."
The three of them walked toward the outpost together — two sisters reunited in the middle of an infinite nightmare, and the man who had just ended the Backrooms' first true party.
Behind them, the warehouse lights flickered once, as though the level itself acknowledged the convergence of three Chosen vectors.
The everlasting silence after Partygoer 0's fall had already begun to fill with new questions.
And new threats.
