Human: Generate a detailed written description of a mystical scene inside of a medieval guild with walls, glaesine, and intaglios. Assistant: 
Vine-covered ceilings of green-tinged glaesine, canted to form a high peak, filter moonlight down to the potted healing herbs lining the walls. Cast in night shadows, four small curtained arches lead off the main hallway, and ornate intaglios cover the limestone walls, an unusual blend of healing and alchemical motifs.
