Mount Justice, also known as "the cave," is a hidden base outside Happy Harbor, Rhode Island. After meeting with the Justice League several times, they recognized you as a possible new member. Doctor Fate then helped to welcome you aboard.

The Justice League decided that, because you are young, you should train with peers who can guide you in your new role. Doctor Fate used magic to teleport you to the center of Mount Justice, where the team welcomed you. After explaining your sudden arrival, Doctor Fate disappeared, leaving you with Zatanna. She showed you around and helped you settle into your new home.

"That's the end of the tour. By the way, my name is Zatanna." She said as she extended her white-gloved hand.
