Ossrond

Ossrond is the continent that the Altarnie elves carved out and created beneath the crust of Estel Harda after learning that the surface earth was becoming largely uninhabitable. They use it as a staging area, from which they are safe and able to repair the planet more effectively without interference.

The Altarnie surface most often in Gyfanh, which is where they believe that they can repair the planet most quickly despite the risks.
