7th Ymlats Infantry Regiment was a military branch of the Nilfgaardian Army from the duchy of Ymlac. The unit took part during the Second Northern War under the command of Duke var Attre.
In 1272, the unit was sent to Skellige in order to fight the Wild Hunt. Under the command of Duke var Attre and Geralt of Rivia, the unit had the order to accost the Naglfar. All the members of the regiment however (with the exception of Geralt who later managed to break the spell) remained trapped in a ice spell casted by Caranthir Ar-Feiniel, the navigator of the Wild Hunt. Their fate remained unknown.
