At the confluence of the great subterranean rivers, beneath the green glaciers and sheltered from the blinding snowfields lies the isolated settlement of Cavetown.
Many generations ago the nomadic tribes of the frozen tundra took shelter in this cave and have remained there ever since- their small band growing into the prosperous settlement you see today.
In the middle, towards the top- you can clearly see the temple garden where the high priests congregate. This is one of only three places in the cave where sunlight reaches, and where plants can grow, giving it great significance to the people. Only during festivals or ceremonies are citizens permitted to enter the garden, and fallen leaves from the holy red tree are worth a half-dozen catfish to the average villager.
To the left of the garden is the temple itself- its many lanterns burning fiercely. A typical example of Cavetown architecture- it uses a strong stalagmite as a central pillar on which the roof is supported- the roofs are thatched with long reeds that grow at the rivers edge in summer.
Towards the bottom right you can see one of the eel pools, where catfish and eels are farmed for food. They are also hunted from the lake far below and from the many rivers and lakes that extend deep beneath the mountains. High above some sacred finches fly. The local people believe the glowing birds are spirits of their ancestors, and tend to spoil them rotten. In return, the birds hang around, and their bioluminescent feathers provide a valuable light source to the villagers.
Light is a big deal to the people of Cavetown- so they adorn their houses with torches blazing with catfish oil, to show off their wealth and status. Light is also a necessity for navigating the precarious terraces and pathways that jut from the cave walls, so acolytes from the temple are tasked with keeping the pathway lamps lighted day and night.
