Gate Classes

Not all hole-teleportation gates are equal. Their scale, throughput, tolerance, and political value vary enormously.

This page defines a reusable canon taxonomy so stories can refer to specific gate types instead of treating every gate as identical.

Class I: Local Transfer Rings​

  • Purpose: limited system-scale transport, cargo shunts, station-to-station high-value transfer
  • Capacity: small craft, containers, specialist missions
  • Traits: compact, tightly regulated, relatively common in advanced systems
  • Weakness: too small for large strategic shipping

These are the smallest practical gate systems and are often embedded in industrial or orbital logistics networks.

Class II: Civilian Corridor Gates​

  • Purpose: routine interstellar passenger and cargo movement between developed systems
  • Capacity: merchant hulls, liners, escorts, standardized freight trains
  • Traits: the workhorse gate of prosperous regions
  • Weakness: expensive to maintain and vulnerable to congestion

Most civilians who have ever used a gate have used a Class II installation.

Class III: Strategic Junction Gates​

  • Purpose: connect major corridor intersections, capitals, and military concentration zones
  • Capacity: heavy shipping, convoy chains, war logistics, emergency evacuation flows
  • Traits: massive traffic-control ecosystems and strong defensive posture
  • Weakness: loss or blockade has region-wide consequences

If a Class III gate fails, trade maps must be redrawn.

Class IV: Fortress Gates​

  • Purpose: military projection, rapid reinforcement, and theater command mobility
  • Capacity: fleet-grade warships and armored logistics streams
  • Traits: hardened superstructure, layered defense, restricted access
  • Weakness: politically provocative and expensive even by great-power standards

These gates are military facts as much as engineering facts.

Class V: Foundational Megagates​

  • Purpose: civilization-defining trunk corridors, intergalactic bridges, or ancient mega-infrastructure
  • Capacity: exceptional mass tolerance and network significance
  • Traits: monumental scale, unique maintenance doctrine, often culturally iconic
  • Weakness: few in number and impossible to replace quickly

Some Class V gates are so important that entire eras are dated by their opening, loss, or restoration.

Special Variants​

Beyond the five common classes, stories may also use variants such as:

  • black-site gates for covert traffic
  • relic gates of unknown origin
  • emergency evacuation gates with narrow load rules
  • unstable prototype gates under scientific control

Operational Differences By Class​

As class increases:

  • throughput rises
  • approach control becomes more militarized
  • political importance rises sharply
  • repair and certification become harder
  • strategic dependence becomes more dangerous

Recommended Story Use​

  • Use Class I and II for civilian life, commerce, and local worldbuilding.
  • Use Class III for contested trade and regional politics.
  • Use Class IV for war planning and major crises.
  • Use Class V sparingly, for places that should feel historic and irreplaceable.
