An ancient temple once used by a society of underground people. It is an adventure location in both Monster Farm Online and Monster Farm Lagoon.
The Kunareya Ruins used to be located in the province of Rusetara on the Eastern Continent, but after its destruction it came to rest on a small island in the Refirn chain. It contains a large mural wall (much like the Promiass Ruins) of the Phoenix fighting Moo.
In Lagoon, it is the twenty-fourth gameplay area, which you visit after Plant Land. The Ruins have 5 parts, each with their own levels: The Entryway (8 levels), the North Wing (7 levels), the East Wing (7 levels), the West Wing (7 levels), and the Back Door (7 levels).
