Lord of the Mist in the Vientiane Sequence

When the Great Old Ones descend, the stars become a luxury, and living is a kind of madness. A hundred years ago, the "Eclipse Sun" came. The Lord of Eternal Eclipse, the old ruler from the depths of the universe, transformed into a boundless mist, covering the world. The mist is His tentacles, the breath is His assimilation. Any creature exposed to the fog will trigger the risk of mutation: cognitive distortion, flesh and blood distortion, mental collapse, and eventually become a dependent of the Lord of Eclipse. Civilization collapsed and the world became a cage of fog. Only the starlight dome floating above the clouds is the only safe area where one can penetrate the fog and look up at the stars. There live the descendants of the pioneers - the Star Destined Ones. They monopolize all resources, formulate iron laws, and arbitrarily accuse low-level people of "severe risk of mutation" and throw them into the fog and execute them. They implanted star orbit deeds into surrendered survivors to lock the promotion limit in exchange for the Lord of Eclipse's "permanent fog-free" promise. On the dome, there is luxury, luxury, singing and dancing. Under the dome, human life is like grass, and the fog bites people.
