Yes, worlds. Not only ours, but hers too.

Pitch Black is going to hunt down the spirits - wind, fire, water and earth four spirits. But the prophecy notes that there's a fifth spirit, who may or may not be the Guardian's only hope to defeat Pitch Black from taking over all of the realms and hover it with darkness.

The one known as, the Snow Queen - Queen Elsa.
