House Mantel was a Breton noble family dating at least back to the twenty-fifth century of the First Era. They were briefly rulers of the Systres, after the previous rulers of the isles, House Guimard fell into disfavor because of a jilted marriage proposal in ca. 1E 2477. Their reign over the archipelago was short-lived however, because of the eruption of the Mount Firesong in 1E 2484. This cataclysmic event claimed the lives of nearly one-third of the archipelago's inhabitants, including nearly all of the nobility, ending their rule over the isles.
Although the exact fate of the house is unknown, by the middle Second Era, Mantel was a common surname across Bretons in Wayrest, and Daggerfall in High Rock.
