Signal

The Signal was a galaxy-wide message broadcast by the Triune in 3 AG to all sentient species. In it, the Triune revealed itself and detailed the existence of a new plane called the Drift and the technical specifications of how to build Drift engines and achieve faster-than-light travel by traveling through it. The divine message took various forms, appearing as inscriptions on natural features, dream-like revelations shared among numerous minds, and ethereal songs captured by satellites. Those peoples who didn't already possess spaceflight technology gained valuable insights from the Signal, potentially revolutionizing their technological advancement within a generation. For those already venturing into space, the Signal's paramount discovery was the technology for Drift travel.

Enabled by the Signal, numerous societies embarked on their initial ventures into the Drift within a few years, and the technology has steadily advanced in both reliability and speed, leading to a massive land rush and an expansion of new economic opportunities. This periodic enhancement captivates Triune's faithful, who assert that the ideal Drift engine blueprint is concealed somewhere within the Drift or the Signal. Unraveling these phenomena and extracting the yet-undiscovered gifts buried by Triune falls to mortal ingenuity.
