Bug Network
A covert mesh communications network designed and deployed by Zet in Chapter 4, built from tiny insect-like physical devices manufactured using hijacked private 3D printers.
Device Design
Each "bug" has five components:
| Component | Function |
|---|---|
| Legs | Locomotion; allows the device to move into position or evade detection on most surfaces |
| Camera | Basic threat detection |
| Extendable antenna | Forms the mesh network; can extend when needed for improved range |
| Processor | Encryption/decryption of signals; routing; basic threat detection and evasion |
| Induction charger | Recharges from publicly available electrical surfaces |
The devices use completely custom hardware, software, encryption, and signal transmission methods — making them very difficult to detect or trace. Zet deliberately excluded any software update mechanism (including one would be too risky to implement).
Manufacturing
Zet sent print jobs to 50 privately owned 3D printers across its district. 31 bugs completed successfully; others failed or were canceled by owners. The completed bugs self-coordinated upon activation, forming the widest-spanning grid formation possible.
Operation
Signals routed through the bug network are designed to be nearly untraceable. Zet cannot see the path a signal takes; bugs do not send confirmation responses. Only the final destination's reply is routed back through the network — accepting a small traceability cost in exchange for functionality.
Initially deployed to carry the Health Agency appeals, removing the risk of the operation being traced back to the TES server.
Limitations and Open Problems
- No update mechanism by design — the software is final as deployed
- Manufacturing at scale is unsolved: private printers are tedious and unreliable; Zet's own printers would require money and a physical location
- Coverage currently limited to Zet's district
Chapter 5 — Confirmed Operational
As of Chapter 5, the Bug Network is actively routing Health Agency appeals, keeping the operation from being traced back to the TES server. No expansion or changes to the network are noted.
