Koorikama

Koorikama is the second largest island in the Great Sea and the largest in the Kwatoka region. It is a volcanic island formed by the Dragon Roost Mountain, a dormant volcano that hasn't erupted in centuries. Most of the island's population is concentrated on the city of Wenahchee, stretching from Dragon Roost to the west coast.

Geography
Koorikama's most prominent feature is the Dragon Roost Mountain, a dormant volcano that sits in the middle of the　island, closer to the west coast than to the east. This caused the west side of the island to have generally much steeper terrain than the larger east side. This proved to not be much of a problem for the Rito, however, who traditionally live in mountainous terrain.

Picori Forest
Picori Forest is a large forest located on the south base of Dragon Roost, to the east of Wenahchee.

Dragon Roost Mountain
Main Article: Dragon Roost Mountain

The island's tallest point. Dragon Roost is a dormant volcano that houses Valoo, patron deity of the Rito and one of the last remaining dragons. Inside of the mountain is a temple dedicated to worshiping the old dragon.

Tohru Valley
Located on the eastern slope of Dragon Roost and snaking its way through Koorikama all the way down to the east coast, it is filled with extremely fast and dangerous winds which carved out various narrow passages on the walls of the valley. Only the most skilled of the Rito dare to fly through it.
