Seleryanna is the sole continent that makes up the highlands (or dandor) that float above the world of Avonia. Seleryanna appeared in the skies of Avonia around the Templaedan year 729, emerging from a rip between the Material Plane and the Plane of Shadow. The people of Seleryanna recall watching the world around them disintegrating into darkness when more than half of the continent was lifted out of the sea and brougnt into the Plane of Shadow. Within an hour sunlight graced the landscape of Seleryanna once again as they glide into the sky of Nostandor.
Currently peaceful exchanges are the most common interaction between the nations of Seleryanna and the rest of Avonia. Many who live on Seleryanna wish to isolate themselves from lovindor, but many scholars and sages push for more open communication between the two worlds, insisting that peaceful relations with the world below will bring prosperity and keep them safe as everyone adjusts to their new reality.
