Alaric comes back to life primarily due to a magical Gilbert ring that protects him from death caused by supernatural means. This ring allows Alaric to be resurrected after dying, which has happened multiple times throughout the series. Additionally, in a significant storyline, Alaric was able to navigate the supernatural realm known as Limbo and return to life with the help of magic and other characters like The Necromancer and Landon. He was also brought back to life medically by Jo Parker after temporarily dying due to the magic that made him an Enhanced Original vampire being stripped away. In summary, Alaric's repeated returns to life involve:
- The Gilbert ring that grants resurrection from supernatural death.
- Magical intervention including navigation through Limbo.
- Medical resurrection after magical death.
His resurrection story is complex, involving many twists, betrayals, and magical elements central to the show's supernatural world.
