The storm is the eternal whisper of Gray Harbor, and Finarfin's young apprentice, Yungsong, known as the "Mast-Mast Carver", builds a fragile defense line on the edge of this violence. On the broken masts of countless sunken ships, he used the power of life to carve mysterious tidal runes in order to appease the angry sea and calm the storm. When the ancient nightmare bred in the deep sea - the forgotten ocean beast reawakens, setting off destructive waves and ransacking the port, the end of Gray Port seems to have come. At the time of life and death, Yongge devoted all his life and soul to the mast that was on the verge of breaking, carving the final character. The talisman culture serves as a giant net of light, binding the giant beast and finally causing the tide to subside. The gray broken mast is reborn as an immortal lighthouse, standing on the shore of the angry sea forever.
But the story is not over yet. When people finally accepted that Song Song was gone, Finarfin, the new guardian of Gray Harbor, discovered something strange deep in the giant network. Yong Ge exists in another form in a death realm that no one dares to imagine. He sets off the tide that reverses the path to new life. The remaining mast is like a lighthouse, its light shining through the dawn of a new era as the storm changes. Within the seal of the sea beast, the talisman carver became part of the will of the ocean, erecting an immortal beacon soaked in souls for future generations at the edge of the abyss between reality and eternal night.
