The archivist found a line of pencil writing at the end of the Ember Star mission log - "The ship rising out of the fog that day was the same color as straw." Fang Yan, Shen Du, and Lin Che disappeared after setting off to explore the fifteenth planet "Eye of the Earth" at the end of the Era. All official records ended with that line of writing. He started with a color code, traced back a disappeared track, and gradually discovered that the same secret was hidden between the desert dusk ceremony, the straw piles on the left-handed planet, and the paving number KF-07 when the base was completed. There are more than just three people missing. There was more than one ship sunk in the sand.
Intention: Those who disappear at the end of the sea of stars leave an invisible trail. What the latecomers want to do is not to commemorate, but to put those forgotten coordinates back on the ground.
