Did it come from somewhere?

``It is said that the human race in this world was originally just one type of human. From elves, orcs, dwarves, and other beastmen to demons, They all come into this world and are transformed by receiving the blood of rare people.\'\' Sylvia is muttering to herself while spreading out books in the reference room attached to the library. \"Hmm, that\'s an interesting theory, but...\" Sylvia tugs at her pointy ears as she looks at the schematic diagram of the Earth Star placed next to her desk. Apparently it happened while he was studying astrology. Few people today doubt that the earth where people live is a star, shaped like a large sphere. We know that the planets that show strange movements on the celestial sphere are also Earth\'s brother stars. “In the structure of this universe, where did that rare person come from?” I muttered as I poked at the floating ball hanging from the ceiling. \"What about the heavenly world? What about the demon world? What about the fairy world? Where is it?\" However, even if we understand the major relationships between stars, there are still many details and depths that are still unknown. \"I guess it\'s magic after all.\" Since there is teleportation magic, it cannot be denied that they came from unimaginable distances and locations. \"I wonder if it\'s a dimensional gate.\" Sylvia twisted her head in thought.
