City of Dust and Light

This is a world shrouded in fog. In this world, only "Children of Light" can ignite fire. Without the protection of flame, you will be lost in the fog forever... ——Or be devoured by wild beasts. This is very common. Here, humans are not at the top of the food chain, nor are humans the only creatures with advanced intelligence. Humans are so weak that they cannot even live in large groups. "Besides yourself, do you think we have any other hope?"
