Zemniaz

 was one of several magically floating cities during the Age of Arcanum that was destroyed during the Calamity.

Zeidel
The society of Zemniaz was known as Zeidel. Much of the basis of the Zemnian language and the culture of the Dwendalian Empire itself stems from this ancient society.

Notable People

 * Halas Lutagran - An archmage who lived in the city sometime before its fall and served on the council of Zeidel.

History
Zeidel was one of a number of extremely erudite societies in the Age of Arcanum that had harnessed crystals to make their city hover aloft. It was a powerful nation, one of a handful of floating mage nations, although much smaller than its contemporary, Aeor. When it fell in the Calamity, the survivors began the early Dwendalian Empire, settling in the area now known as the Zemni Fields.

Trivia

 * One of the books found by the Mighty Nein in the Happy Fun Ball was called Public Debate Records: Forum of Zeidel, regarding the moral implications of arcane experimentation on prisoners of Ghor Dranas and warnings of the war with the gods.
