Gate Builders

Architects of the rings who vanished before humanity discovered their network of over 1,300 gates.

The Gate Builders were a long-dead alien civilization responsible for creating the ring gates, an artificially sustained wormhole network that connects thousands of star systems. These structures allow humanity to travel between solar systems instantly, bypassing the light-speed limits that previously confined them to the Sol system. Their legacy is defined by the ring in the Sol system, a thousand-mile diameter structure located two AU outside the orbit of Uranus, which serves as the gateway to a hub of starless space approximately one million kilometers across.

Quick Facts

Primary creation: The Ring Gates (Wormholes)

Lore & Background

The ring gates and the protomolecule are the legacy of an alien civilization that built them long before human expansion. The Sol system gate leads to a central hub referred to as the "slow zone" after the third novel. This hub contains more than 1,300 other rings, each opening into a different star system. In the center of this hub stands a highly defended alien space station that controls the gates and can set instantaneous speed limits on objects inside to act as defense mechanisms. Despite human access to thousands of new worlds through these rings, the builders themselves remain absent, having created this network for unknown reasons before their extinction.

Reader's Guide

The discovery of the ring gates transformed human civilization from a single-solar-system species into an interstellar one. The Sol gate is located two AU outside Uranus and leads to a hub where speed limits can be imposed by the central station. With over 1,300 rings available for travel, humanity gained access to thousands of new worlds instantly. The network remains a mystery, with the central station serving as both a gateway and a defensive mechanism that enforces order within the slow zone.
