Phantomia, I'd assume

My brain was trying to make it Ghostium or something like that. But that one does make sense.

So imma little confused bout some pokmon have multiple types,so let's say i have a dark/grass pokmon like decidueye where would i go?

You would go to which ever one you'd want to go to. As long as it is one of your Pokemon's types.

For Decidueye, he would either go to Phantomia or Forestian.

Either kingdom is alright.
