Mountains of the Sun
Mentioned in Moving Pictures, this is a mountain range which runs roughly rimward to hubward and divides the country of Klatch from the wilder interior of the continent. The Tsort river rises from the hubward end of the range. They extend down into the Kingdom of Howondaland and a shadowed valley in their fastness is the last refuge of the imperilled N'Tuitif tribe.
On Roundworld, the Mountains of the Moon were a semi-mythical mountain range in Africa where the source of the Nile could supposedly be found, now more-or-less identified as the Rwenzori Mountains on the border of Uganda anf the Democratic Republic of the Congo.
