Mithim is a country located in southeastern Zarhanna, on the world of Lezaria. It is the homeland of the gnomes of Lezaria, although there are a number of elves that dwell there as well.

The Endless Plains lies to the west across the River Galsidh. Tregas Valley and Dragora lie to the north and northeast across the mountains. The Mirandarine Ocean stretches to the south, and there is more ocean to the east as well.

The capital and largest city is Dherdem, at the mouth of the River Galsidh. Daggervale, located in the mountains in northwestern Mithim, is the magical and technological center of study on Lezaria.[1] Many elven mages took refuge there after Sardill's rise to power.[2]
