When we arrived at the mountain, Helga quickly guided us down a path she and the dwarves had made with their amazing mining skills and earth shaping skills. Apparently not only they made a cave but even crafted stairs to move down easily. The caves were illuminated mostly by special crystals that generated light and also mushrooms. I had thought about picking a few, but Helga said that aside from their luminescence, they were not valuable and it was better to let them be there to illuminate places.
They were certainly more convenient than putting torches that will eventually get the entire cave with the smell of burnt wood and oil, or magic items that will eventually run out of magic and will need constant replacement like torches.
"But aren't these sold elsewhere?" I wondered.
