In his fruitless search for a door, he had found large, black, stone constructs lining the walls. Occasionally, he would find gems and gold coins on top of them so, seeing no reason not to, he pocketed them. There was rather a lot to gather and soon his spacious pack was beginning to feel rather full and heavy. Sighing in frustration, he saw no other way to go so, with the utmost care, he descended to the next level. Landing heavily, he got back to his feet. Like the floor above, this floor was the same story. Search for an exit, fail, open doors to let in light, try not to fall into random manholes, loot shit, go in circles, descend in frustration.
