Tatuln Peninsula

Tatulnia within the context of the Seranias; the black star shows the location of the eponymous city of Tatuln.

The Tatuln Peninsula is a region of subcontinental size in north-eastern Serania Major; an alternative name is Tatulnia (often used in Sabamic languages). Its name originates in the Agamari settlement of Itätūlenn, now the Zepnish city of Tatuln, which was conquered during the Heathen Wars.

The region is largely contiguous with eastern Zepnish Serania though it also hosts the only interordinately recognised sovereign state in Serania Major, New Issenov. The southernmost region of the peninsula is part of the colonies of Tassedar. Agamar holds two small territories along the north-eastern coast: Vartijaniemi, close to the Roriks Gulf, and Kotkansāri, on a small archipelago that forms the easternmost point of northern Serania Major.
