"I don't really know what they are, just that they apparently aren't 'mortal'," SubZero considered the next question from Ami, and counted up all the realms that he knew about.

"No idea, but I know of four, including my own. And I don't know the name of whatever place we're currently in. I was traveling through a portal to the netherrealm that accidentally dumped me here instead. There's also whatever realm you're from, probably one that's just like mine," Were there multiple realms just like his? It made the most sense considering what he knew about this place.
