Hades is also known as the husband of Persephone, the goddess of spring and queen of the underworld. As the ruler of the dead, he is responsible for guarding the gates to the underworld and ensuring that mortal souls reach their final resting place. Despite his dark and somber reputation, Hades is also seen as a fair and just ruler who enforces the laws of the underworld.
