Sumifa is a city of the ancient nation Almaaz on Terisiare that was ruled by a Pasha. During the Brothers' War the song-mages of Sumifa joined the war on the side of Mishra, in order to avoid the ruination of their homeland. Sumifa is thought to have been destroyed during the Brothers' War, but was refounded after the Ice Age.
It is here that the book Song of Time takes place.
