New Continents is an umbrella term used for the continents of Melania, Delgamia, Fiarria and Nuarmia, as well as Maritimia and surrounding island land forms, including Lexicon and Svarthaedir, amongst others.
Nuconia (not to be confused with either Nuropia or Numelia) is an increasingly popular name for the same region. It describes the entirety of the "New Continents" of Nuarmia, Fiarria, Delgamia, Melania and Maritimia and surrounding islands. The name Nuconia is derived from "NEW = NU-" and -CONIA for "CONtinents".
Other commonly used name for the same grouping is Vexanova, and in Utameyas the region is called the Sapkone'i.
