Primeval Grotto (Japanese: 太古洞穴 Primeval Cave) is an area located in the central region of the Coronet Highlands of Hisui. Its entrance is located north of Celestica Trail.

It is the only known place in Hisui where Origin Ore, as dubbed by Professor Laventon, can be found. The Miss Fortune sisters seek to steal all of the Origin Ore in the cave during Mission 18: "The Counterpart".


The area of Primeval Grotto is composed of two parts: a forest and a grotto. The forest is in a long stretch of valley between Celestica Trail and the base of the Sacred Plaza.

Within the grotto, there is a small cavern located inside of a small cliff. There are two entrances, each leading into a different room of the cave. From the southern entrance, a large vein of glowing red Origin Ore is visible to the right, embedded within the cavern wall. The second room can be accessed from the first room or from the western part of the grotto. In this room, there are the bones of what seem to be a Rampardos and a Bastiodon unearthed from the northernmost wall.
