This was to prevent any invaders from attacking his people, but to make sure that his subjects did not attempt to leave the island, Karl implanted memories into the Eldians of Paradis. Now all Eldians believed that the island of Paradis housed the last remaining people on Planet Earth. But when a young girl washed up on the shores of Paradis, their beliefs were shaken.
