Tapfer Aeterna, officially the Federation of Tapfer Aeterna, is a Natopian demesne in the continent of Tapfer. Its capital is the city of Chancellorsport, and its most populous city is Frenzyville. The Tapfer Aeterna demesne is known for being considered as the "Natopian holy land"^[2], due to Nett Opaegh, the mythic founder of Natopia, who was believed to have been born and lived near the city of Nettivity. It borders the demesnes of Arboria del Sur and Transegale to the south; the demesnes of Klaasiya, Ptia and Ziegeland to the east, and Dos Gardenias to its north, and the nation of Calbion to its west. As of 1732 AN, it has a population of 83,477,198 residents, making it one of the most populated demesnes of Natopia. The demesne contains 6 of Natopia's largest urban centers alone, the cities of Frenzyville, Chancellorsport (its capital),Cape Cran, Port-du-Meir, Guaynabo, and Nea Lindstrom.

Tapfer Aeterna is also known as Thalassa, which was the name of a demesne constituted from Tapfer Aeterna's territory in 1609 AN^[3].
