Hastily-colored sketch of the latest horrible fantasy city from my brain. Built inside the trunk of a petrified-but-still-alive tree. The nutrients the Tree moves around are tapped and used by the people. That's how people get water and soil and stuff despite everything being rock(?).

The air here glows instead of there being a sun. Probly due to thaumophytic aeroplankton that have a symbiotic relationship with magic floating algae. Or some other nonsense.

Mostly it's just an excuse to draw well-lit caves with fans in the ceiling.

Dunno. Might discard it. Might reuse some elements. Might connect it to that point-and-click game I saw in a dream once.
