The inside of the rock was extremely dark. Empty torches stood on the walls, burned out either by time or by something else. The only light came from the opening, where the searing sun burned down towards the ground, threatening to ignite everything that it could see.
To make up for the low level of light, Marcus summoned a flame into his hand. Now imbued with the power of sun magic, his fire burned brighter than it ever had before, and perfectly illuminated the space inside the rock.
The walls inside the rock were clearly carved by human hands. They were all cleanly cut, flat surfaces and there was none of the randomness that a natural formation of rocks would contain. Supports, dredged up from the ground they stood on, were placed in key locations to prevent the collapse of the rock while the mine would be in use. Despite them being old, they stood firmly against the walls, just as they had for an unknown amount of time.
