The Mountain Near Hama’s Village
A lot of the Fire Nation’s landscape is modeled on Iceland. Hama’s village is no exception. The mountain in the background is based on the Herðubreið mountain. (Art Book, p. 147)
Herðubreið (Icelandic pronunciation: [ˈhɛrðʏpreiθ], broad-shouldered) is a tuya in north-east Iceland. It is situated in the Highlands of Iceland in the midst of the Ódáðahraundesert and close to Askja volcano.
