From publisher blurb:
An overgrown cloister. The outlandish thicket in which it stands springs from walls encrusted with blooms of crystal, phenomena studied by an order ensconced within. They too are transforming.
Condensed to one page for slipping in among other materials, this sandbox-oriented content is intended as an easily absorbed framework for improvisation to be adapted by the user as preferred for a wider setting and specific system.
It presents core ideas and key numbers to fall back on, with general approaches that can be applied in other situations.
The content covers map generation on the fly for an abstracted cloister as well as suggestions for aspects of the locality, including growths, occupants, rooms, volumes and physical changes.
A possible source for the phyme is given in For the Tears of Stars are in Full Flood. The cloister could be simplified or extended using map elements from Landscape: The Manse.
