Streetlamps, fans, and nice music.
The Ceiling (天井, Tenjō, Ceiling) is a dark area slightly lit up by small streetlamps. It can be further lit by using the Lantern effect.
- Heading south-east from the entrance you will encounter a group of streetlamps surrounding a brown door that leads to the Cultivated Lands.
- North and slightly west of the door to Cultivated Lands is an entrance to a small greenhouse, where there is a green rectangular object Urotsuki can interact with, but which does nothing.
- Going south-west this time, there is a small pointy pillar. If interacted with, it will teleport you to Lotus Waters.
