The Star Map is an ornamentation built into the ceiling of the Church. Sometime between Baten Kaitos Origins and Baten Kaitos: Eternal Wings and the Lost Ocean the map was destroyed and its pieces were stolen and scattered the across the world. In Baten Kaitos: Eternal Wings and the Lost Ocean, the party is tasked by a Church attendant with collecting the Constellation Magnus, which contain the scattered stars, to restore the map to its former grandeur as one of the game's major sidequests.
In order of Magnus listing:
- Ursa Major
- Corona Borealis
- Piscis Australis
- Corona Australis
- Ursa Minor

Magnus are rewarded for each of the first constellation returned as well as for reaching certain milestones:
- Every constellation in the Star Map is a real constellation.
- The last Constellation Magnus obtained, Cetus, is the constellation in which the star Baten Kaitos is located.
