Surotsi is the southern continent of the Aulesiri Empire, extending from the Prophet's Deed and Shulensi's Spires in the north to the Fallowlands in the far south. Somewhat smaller than its northern neighbor, Jyotnun, Surotsi's climate exists in a narrow range: Mediterranean on the northern coasts, and desert nearly everywhere else. Most of the continent is dominated by long and level plains, split by small mountain ranges.

Though colonized by the Aulesiri fairly early in the 8th century AR, Surotsi remains a continent mostly populated by the indigenous Esurkish people.
