Sea of Clouds

Guyun Stone Forest is an archipelago of seven large islands and smaller offshoots. The northernmost island houses the Geo Hypostasis, and the island to the southwest holds the Domain of Guyun.

According to legend, this is where Rex Lapis defeated a god and sea monster known as Osial, and the jagged cliffs protruding from the islands at Guyun are in fact the remnants of the stone lances he used in that battle. It seems that those who spend the night at Guyun Stone Forest may experience Osial's memories of its defeat;^[1] whether this is caused by Osial's power or another phenomenon is unknown.

Before the Archon War, Rex Lapis brought his people south of Mt. Tianheng, to found what is now known as Liyue Harbor. They tried to expand their city to Guili Plains, but after Guizhong died during the Archon War, they moved back to Liyue Harbor.
