As they neared the heart of the island, they discovered a vast, empty chamber. There, they were met by a figure known only as The Architect, who claimed to have designed Regret Island as a refuge for those like them. The Architect explained that regret was not a burden to be carried but a lesson to be learned. The true regret, The Architect emphasized, was not in making mistakes but in letting those mistakes define one's existence without seeking redemption or growth.
