Controlled Adjacency / Prepared Transit

Worldgates & Horizon Networks

A Worldgate does not open anywhere by casual command. It changes which prepared regions are physically adjacent—under synchronization, verification, energy, quarantine, and causality constraints.

Prepared Nodes

Passenger and freight operations require registered mouths, verified destinations, rated throughput, environmental matching, and network-wide chronology certification.

Horizon Conversion

Black-state ingress and white-state egress are engineered causal behaviors of wormhole-like infrastructure, not ordinary natural black and white holes.

No Gate Is Safe Alone

Two individually safe gates can form an unsafe global loop when combined with ordinary travel, gravitational time offsets, or moving mouths.

Story Possibility

Distance stops being protection

Trade, rescue, migration, medicine, governance, and cultural exchange accelerate—along with contamination, coercion, sabotage, and the ability of one failure to propagate across worlds.

Civilizational Rule

Connection requires more than benefit

No link opens merely because two places would be better connected. Their ecological, biological, causal, and political systems must be able to survive contact.
