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 existance of a new dimension called the Drift and how to 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 without spaceflight technology gained valuable insights from the Signal, potentially revolutionizing their technology within a generation. For those already venturing into space, the Signal's paramount discovery was the technology for Drift travel.

Enabled by the Signal, societies embarked on their initial ventures into the Drift within a few years, and the technology has steadily advanced in both reliability and speed. 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.
