The rules

1. Floors are fogged. Cartography charts zones (a Task); Maps are items (SYS-28). Uncharted zones can be entered by walking; you just don't know what's in them.
2. Hidden zones exist on every floor (one at least): found by Mapping adjacent zones to 100%, by a Clue, by a Draft's hint, or by an Erratum's landfall.
3. The Deep Atlas: Depth keys map to a lattice per floor; regions grant permanent Depth modifiers when completed; the Atlas is the endless breadth loop for dungeon runners.
4. Archaeology (Excavation): Draft seams yield relics, Drafted items, and pages of prior Seasons; the lore of what was rewritten is dug up by players.
5. Shortcuts (Building + Cartography): players build stairs, ropes, ferries between zones (a Hold benefit), some requiring skill levels to use.
