Ember Abyss and Starfire

The buildings collapsed, the spirit became disordered, and the three realms flowed across the world. All sentient beings carve bones into trenches to survive the cold years. The whole world is climbing towards the light, but he is walking towards the sinking place alone. The floating world is in decline, the undercurrent is rushing, everyone is looking for a way out. The ground is never an abyss, but a broken way back.
