Marl Kingdom

The Marl Kingdom game series is notable to the Disgaea Universe for contributing the character Marjoly along with items named after her vassals, Crowdia, Gao and Myao who are characters in this series. The game series also contributed the Rosen Queen line of stores, as Etoile Rosenqueen is introduced in Rhapsody: A Musical Adventure.

Like La Pucelle (which contributed Priere & Baal to Disgaea), Marl Kingdom was a series also produced by Nippon Ichi which set up a lot of the ground work in terms of gameplay.

The notable games in this series that Marjoly hails from are the prequel Hymn Princess of Antiphona and the original game that comes after it chronologically, Rhapsody: A Musical Adventure.
