Howl's Mobile Black Tower

The time traveler came to a different world, possessed by a disabled dragonborn, and found himself in a black tower. A magical black tower that can run away. Next to him is a gray-blue girl with a strange temper who calls herself "God". The door in the tower leads to the whole world: human villages, elven kingdoms, the land of the dead, the holy city of the Theocracy... And even the underworld. From then on, he was forced to take in a bunch of "problem residents": —The skeleton who loves to make bone soup (always secretly runs to the Theocracy of Light at night); —The village girl who claims to be an eagle-man is actually an angel (who doubts her own god all day long); —A boy of mixed race between Goblin and Elf (who can practice both combat and magic in a few months); —The dark elf (male) who escaped from marriage; —Tauren Mage (this is a bit much). Until the tower became the center of the world.
