Location verbs are actions that each run location adds to the Basic actions. A room lists them; anywhere else the engine refuses them with "Not something you can do here." Companions never use them. They give each location its own main mechanic, as the user asked on 1 November.
Seal#
Vessel Margins · action · clip long-reach
Seal a leaky vessel wall in reach. It stays closed for this round and the next. Overstay: sealing the same wall three rounds in a row costs its astrocyte endfoot; the wall then leaks 1.5× faster and the bonus is lost.
- In the brain: microglial processes can help close a barrier breach (Lou 2016), and staying too long can cost an astrocyte endfoot (Haruwaka 2019).
Trim#
Quiet Tracts and the Tag Garden · action · clip engulf
Trim an input or a misplaced sheath in reach. A cut is final: there is no Undo after it, but Rewind still works. In the Tracts, trimming a misplaced sheath gives that sheath back to its oligodendrocyte. In the Tag Garden, you trim quiet inputs and keep active ones.
- In the brain: microglia nibble pieces of terminals (trogocytosis; Weinhard 2018). Pruning is healthy development, not damage.
Process#
Quiet Tracts · action · clip recovery
Tend and Engulf put the debris you clear into your load, up to 3 clumps. When the load is full, Tend and Engulf are refused: "You can't take in any more: process what you're carrying first." Process empties the load.
- In the brain: phagocytes overloaded with myelin debris stall repair (Cantuti-Castelvetri 2018). The cap of 3 is fiction.
Related Tracts rules#
- Pull-drag: a Sentinel's Anchor & Pull aimed at a clump 2–4 tiles away drags it up to 2 tiles toward you.
- Support: end your turn beside a waiting precursor to shorten its wait by one round. It is passive; you choose where to stand.
Development#
Claude B built these engine verbs on 1 November, after the user approved the location pages. They are in the alpha engine and used by its Vessel Margins and Quiet Tracts rooms.
