The Tumunzari Hills (pronounced too-mun-ZAH-ree) are a rugged region of mountains and hills in western Thadria, near the Bay of Ertan. Now mostly covered by grasslands and exposed rock faces, the forests of the Tumunzari Hills were long ago felled for material to build the nearby cities and for fuel to power the forges of the dwarven communities.
Long home to a dwarven population, today the Tumunzari Hills are part of the Viridian autonomous province of Tumunzar. The dwarves that live there are some of the greatest smiths in Viridia, assisted by the use of ancient forges they brought back to life.
