Tenuvians

The Tenuvians (Tenuvii) are a Thinling nation who settled on the Thinlands after the Exodus. They were one of the Twelve Nations who fled to the Thinlands. They live throughout Tenuvium, are a constituent nation of the Foederatio of Centum, and are largely Western Mormons.
They were historically one of the most advanced civilizations in the Westhold both prior to and during the Bloatfall, with respected military, political, scientific, and artistic accomplishments. Their ethnopolis at the Red Citadel was the most sophisticated settlement in the Thinlands for some time.
Their language is often referred to as "Italics", because it's always written in italics.
=== Behind the Scenes ===
The Tenuviums are based primarily on Italic cultures, an amalgam of both Roman and later Italian nations. Their language is represented in Bloatcraft via Latin, and their ethnonym derives from the Latin adjective meaning "thin", "fine", or "slender", which is tenuis.
