My 7 wonders

Dear Lizzie,

I don't have much time left, they're coming after me. I'm writing to you now because I have a task for you, one I've been selfishly keeping away from you for too Long. Inside the box is a necklace,my necklace. Its not an ordinary necklace,it holds a very sacred power Lizzie, the power to teleport to other realities. Our reality is labeled as the Prime. There are 7 other realities which are the duplicates of ours, each with their own uniqueness.I know this is a lot to take in, but I'm giving you this now because the other realities are fading away. Without the others, our reality would perish too. I want you to travel to the other realities, find their seven leaders and help them save their realities.But of course it's not that easy, the people chasing after me,you must be careful of them. That's all I can say for now. The fate of the worlds are in your hands now,Lizzie. Take care, and know that even if I don't make it out alive, I still love you notice matter what.
(P.S find Fernández, he'll be waiting for you.)

Yours truly,
Beatrice H.
