No, they're not. I promise. The reason Priya's family is down there is because she was born in this dimension. She traveled here to Galador from Earth. She wasn't brought here by the gem like we were. None of us that were brought by the gem are from this reality.
I know it's kind of confusing but there are a whole bunch of different variations of the universe out there. Each a little bit different. Normally they don't mix, but when the gem got messed up, that changed a little.
I can try to explain it to you better in person during our next appointment, but I can absolutely promise you that your parents are not on the Earth in this universe.
