Deltarune Christmas
Castle Town is in the Closet Dark World. It houses Ralsei's Castle and the Fountain of Darkness. It is unique in its ability to host Darkners from other Dark Worlds without them petrifying.
Initially, Ralsei is the only inhabitant. At the start of Chapter 2, Kris transfers residents of Card Kingdom to Castle Town. With the town populated and transformed, the name in the SAVE Point and the theme changes to My Castle Town.
