The Old Mine

This is a small mine, that can be functional or abandoned. It has two points of special interest. 

First place is a larger cave with some mining equipment. Here the characters might even find some raw valuables originally mined from the tunnels and some tools that are still usable. 

The second location is another large cavern with a small pool of water at the center of it. Here the miners started to dig a tunnel, but found something buried deep underground. A sarcophagus or a coffin of sorts.
