The Eye of Elena is a magical amulet that protects its wearer from dark magic. It is also the key to Erawan's tomb. It is also the Lock, the only thing seal back the Wyrdkeys into the Wyrdgate. Mala Light-Bringer had created originally to send back the gods to their realm with Erawan so that he could be destroyed, however Elena wasted to contain Erawan for a millenium. Because of this, the gods stated that Mala and Brannon's bloodline would have to bleed again to create a new Lock. This meant that Aelin Ashryver Galathynius would have to die in order to create a new lock, and Elena would have to help her. Afterwards, Elena would die, and not go to the Afterlife or Hella's realm, she would be lost forever.
