"The mine"

The slope goes down in the lower level that can make the connection with the largest sectors. Warning, the quarry and especially this level is full of holes in all kind. So please pay attention, thank you.

This room was called the Grand Rex because of his height and the sloping floor in tiers remembers a famous parisian movie theater. In winter, there are many bats in this quarry, thank you not to disturb them!

Many thanks to Katafille for being my model this night.
