Sphaera is an Earthlike world with three major continents: Sikano (south), Arokha (northwest), and Eren (northeast). Thalassaterria, the massive island chain to the northwest of Sikano, is sometimes counted as a separate continent due to its size and tectonic characteristics.
Sphaera hosts a wide range of nations and geopolitical powers, from the rigid borders of the Tyerian Empires to the loosely affiliated tribes of kawataro in the southern hemisphere.
Thalassaterria
So large that it is counted as its own continent in many geographical texts, Thalassaterria is an immense tropical island chain to the northeast of Sikano.
