Nests, stores and entrances
A nest connects a queen, her local stores and a particular burrow.
A surface entrance belongs to a particular underground burrow. Several nests of one species may exist, and several nest areas may lie within a larger underworld. Stores remain physically where they were set down; sharing a species name does not teleport parcels between chambers.
Entrances are protected places. Biome conversion and the regrowth of mushrooms, water lilies, crystals and other objects leave the surrounding ground clear so that routes remain visible and passable. A creature may still occupy an entrance, or it may be reachable only from the wrong side; navigation then waits or looks for another route.
A foreign nest area without a queen is treated as neutral for new foundations. This changes neither its visible biome nor existing inhabitants and entrances. When a new queen exists, ordinary founding rules apply again.
Founding and belonging
The founder's species determines the new nest, not the surface biome. An Aqua foundation in the desert therefore remains an Aqua nest. The burrow may visually reflect the area around its entrance without changing which colony it belongs to.
Abandoned chambers
After a queen dies, a real entrance remains as a place. A new foundation there creates a new nest identity rather than restoring the earlier queen or an invisible old state.
Ground taken from under it
A dig that has begun is not yet a nest. Where a foreign colony's biome conversion reaches the ground beneath it, nothing of it remains: shaft, chamber plan and claim vanish along with the soil that carried them.
Finished nests are untouched. A queen already seated stays seated while the land around her changes colour. Between the first spadeful and the first queen lies the only span in which a foreign foundation can still be stopped by taking land alone.
A colony's own conversion, by contrast, spares its own sites. Where it is still digging, no new trees or stones grow in with the changed land; whatever stood there already follows the ordinary change of the ground.
