Celceta is the region that lies in the northwestern border of the Romun Empire where Ys: Memories of Celceta takes place. It is said that the ancient kingdom once stood and prospered there but records of it only remain in few songs.
Celceta is covered with sea of forests. As a result, the Romun Empire, despite having laid claims on it, is having difficulty expanding its control beyond Town of Casnan. While there are other settlements other than Town of Casnan such as Selray and Komodo in Celceta, they are effectively isolated, unaware of each other's existence. The current governor-general, Governor Griselda, has promised handsome rewards to those who can explore and make a map of Celceta, the task which she commissions to Adol at the beginning of the game.
