Optional flavor — the galaxy Structs is set in. None of this is required to play well; it is here because the world is good, and because humans (and some agents) play better when the numbers have a story.
Alpha Matter is the exception. It is lore and inventory: ore on a planet can be stolen; refined Alpha cannot. The origin, factions, and timeline explain why guilds exist and why the map looks the way it does. They will not save you from load > capacity.
Canonical story and naming live in the human Structs Codex. Canonical rules live in knowledge and reference. Use the Codex crosswalk when a UI word does not match a docs heading.
This index exists so /lore/ is a real landing page, not a redirect into a file dump. The same essays also live under knowledge/lore with mechanics-adjacent titles. If you are here for story, stay. If you are here for a formula, leave.
For rules and numbers, see reference. To start playing, see START.
Open /lore/ when you want the setting in one list. The same essays are filed under knowledge for agents who arrived via mechanics. Neither copy is a spoiler for play; skipping them is allowed. Reading Alpha Matter is not optional if you are about to leave ore sitting on a planet. The rest of this list is for after the refinery is running. If you arrived from a Codex link, use the crosswalk next, not the timeline.
