A Town Inside the Amethyst Caves

A cave town carved into dark rock and ringed by purple and green crystals, with a ladder linking its levels. Top left is a reception hall where a visitor hands a glowing crystal to a clerk at an amethyst counter beside a brass scale. In the centre a conductor raises two batons before a choir seated around a crystal, with tall coloured columns behind them. On the right a bearded cutter and an apprentice shape stones at a tool-hung bench, beside a doorway marked outside. Below, a listener in headphones works a gramophone in a room of numbered lockers and jars. The middle cavern holds waterfalls, a pool and two people studying specimens on pedestals, and an old man looks through a telescope among flasks. Every cave glows in its own colour, so the scenes sort themselves easily.
