Primeval Grotto

9 Pokémon can be caught at Primeval Grotto in Hisui.

Primeval Grotto, entered from north of Celestica Trail in the central Coronet Highlands of Hisui, pairs a long forested valley below the Sacred Plaza with a small two-room cavern set in a cliff. It is the only known source of Origin Ore in Hisui, named by Professor Laventon, which the Miss Fortune sisters attempt to plunder during Mission 18. A glowing red vein of the ore is embedded near the southern entrance, and the second chamber holds exposed bones apparently belonging to a Rampardos and a Bastiodon.
