A crescent-shaped valley at the base of the Zehn Mountains that sections it off from the coastline of the island. It is the twenty-eighth gameplay area in Monster Farm Lagoon, unlocked after your battle with Moo in Tochika. Because the game was discontinued before this area was finished, it is unknown how many levels it was intended to have, but it has at least 3.
It gives way to flat area used for practice battles, called the Arlem Training Ground.
