Lazarus Pits are fictional rejuvenation pools found in the DC Comics universe, primarily associated with the character Ra's al Ghul. These mystical pits are said to have the ability to restore life to the dead and heal severe injuries, making them a powerful tool for those who seek immortality. The waters of the Lazarus Pits are infused with unique properties that can revive individuals, but they often come with side effects, such as madness or a violent temperament. This duality makes the pits both a blessing and a curse for those who use them, adding complexity to the stories involving Ra's al Ghul and his quest for eternal life.
