Astrocyte
In the alpha Cell type · facts checked 2 November 2026
Astrocytes are star-shaped glial cells that support neurons. In Arborwake they are anchored residents: their processes reach out, but their bodies stay put.
In the brain#
The points below follow the dossier's sources, simplified.
- Astrocytes help keep the space around neurons stable. They take up excess potassium and the signalling molecule glutamate.
- They support neurons' energy supply.
- Their fine endings, called endfeet, touch blood vessels and synapses.
- Their work is real, local and complex. The dossier notes that these studies do not support the game's errands, requests or equipment.
In the game#
- Anchored. Stella at Hearth and Aster at Starwell never travel. Their support covers one area and cannot protect every route.
- Support is not a cure. Astrocyte support buffers a local burden. It does not clear the source or switch off inflammation everywhere.
- Supported ground. In turn rooms, an astrocyte process can rise through a floor opening to support a tile. See Supported ground.
- Calming visit. The Apothecary's calming service shows an astrocyte tendril poking out of the ground with sparkles; no astrocyte body walks to Hearth (user, 1 November).
- Attune. A Warden can learn Attune at a real astrocyte link in scene II2.
Development#
- The side-view astrocyte NPC was approved on 1 November (1.5× the Ranger, no nubs or antenna). Astrocyte tendrils went through several rejected looks before the current rope style.
- Named designs for Stella (B) and Aster (B top, A side) were approved on 2 November but are not installed.
- In the alpha Generic astrocytes appear in the Placeholder alpha overworld and encounters.
