The Jedi Temple on Lothal had a portal that led to the world between worlds, containing countless other portals that could be accessed across the space-time continuum. Ezra Bridger heard voices emanating from many of them, and witnessed the duel on Malachor between Ahsoka Tano and Darth Vader through one of these portals.
Bridger soon found that he could interact with them and in doing so, was able to save Ahsoka by pulling her through the portal into the world between worlds. Due to Ezra's interference, the veil between dimensions was weakened and Palpatine was also able to peer into it with the help of Sith magic. However, he could not physically enter and needed Ezra to fully access the power the dimension held. After having fought off Sidious's attempts to capture them, both Ezra and Ahsoka returned back through the portals they had come from, with Ahsoka returning to Malachor and Ezra back to Lothal.
