In Wolfram’s Parzifal, a city in the realm of Duke Lyppaut.
It was the site of a battle between Duke Lyppaut and King Meliant of Lis after Lyppaut’s daughter, Obie, refused Meliant as a husband. After a day of fighting in which many good knights were brought down, Gawaine, fought on the side of the defenders, Percivale on that of the attackers.
Peace was made in due course, Obie’s little sister, Obilot, playing an important role.
