The Root

The descent takes six hours.

Soll leads. Their filaments cast enough light to see by, and they know the Underbelly's upper corridors from weeks of trips with Diego. But past the control room, past Lena's lab (which we skirt carefully, taking a side passage Diego mapped on a previous trip), we enter territory none of us have walked.

The corridors get narrower. Colder. The Architect glyphs on the walls shift from the flowing equations I've been studying to something denser — recursive patterns that reference themselves, loops within loops, functions calling functions. If the upper-level glyphs are application code, these are the kernel. The operating system.

My phone died two hours ago. Battery drained by the constant scanning and note-taking I've been doing since we arrived. I'm working from memory now, and the physicist in me hates it — hates not being able to record, annotate, model. I feel blind without my tools.

But the patterns are sinking in anyway. My brain won't stop parsing them. The recursive structures are describing something — a protocol. A set of rules that the gate network follows. Not the monitoring. Not the throttling. Something deeper. Something foundational.

"Soll," I say. "What are you feeling?"

Soll's filaments have been shifting in patterns I haven't seen before — rapid cycles of color that don't match any emotional state I've learned to read. They look disoriented. Almost overwhelmed.

"It's... dense," they say. "Like standing in a crowd where everyone is speaking at once. Not words — structures. Shapes. The walls are broadcasting. They're describing the architecture of the network at a level I've never..." They trail off.

"Can you understand it?"

"Pieces. Fragments. It's like trying to read a river."
