Mina shakes her head. Those are questions she didn't even know she could ask. She did hear someone mentioning it'd be easier to give names to all the different Earths, but it all sounded really technical to her.

"Uhmm, I don't think universes and planets have like... a specific designation like that? I mean, in my planet nobody knows there are other Earths or dimensions, so we only called ourselves Earth."

But! She nods quickly. "Metas is short for metahumans tho! They call us that because we have powers. Sometimes the Confluences even give us new ones, or give the natives powers too, so they become Metas as well. That's why things can get so crazy." People who have just arrived are given new powers, or people who never had them are given new powers... it's naturally chaotic.
