Frastinia is a tropical subregion of northern Cordilia surrounding the Astro Sea and the Serevan Sea. The term “Frastinia” as a region may refer more narrowly to the northern peninsula from western mainland Gianatla to the eastern border of Holy Free and the northern border of Eflad, or more broadly may extend from Puerto Pollo and Bruuma to Besern and Erinor and Sereva.
