Frontier Exploration
Last updated: August 21, 2026
The Frontier surface is where you explore sectors and systems in the persistent world. Exploration in Terminus is a resource decision rather than a free action: it consumes what could have been spent elsewhere, and it returns information. In a game where colonies are claimed from a shared and unstable frontier, information is the thing that makes every other decision cheaper, which is why exploration tends to reward players who treat it as infrastructure rather than as an interlude.
Sectors and systems
The frontier is organised the way Xdripian space is organised everywhere: spheres contain sectors, sectors contain systems, systems contain worlds. That hierarchy is the same one the Celestial Atlas renders and the Codex documents, which means the vocabulary you learn here transfers to the rest of the Universe.
Exploration and claim
What you survey becomes what you can consider claiming, which is why the colonies register lists surveyed and unclaimed worlds alongside held ones. Exploration and expansion are one pipeline seen from two surfaces.
Instability
The frontier is described as unstable, and a persistent shared world makes that a live property rather than flavour text. What was true when you surveyed it may not be true when you arrive.
The Celestial Atlas is the Universe's own map of the same spatial vocabulary. It is not a Terminus tool and holds no game state, but it is an excellent way to understand what the words mean.
