I'm not sure.So I take it this Cloud planet is Middle Earth? That explains the elf.
I got the impression from next weeks preview that FREECLOUD is where Maddox is supposedly hiding, not where Elnor is.
(Picard asks Elnor to come with them them)
Also, Raffi didn't say that FREECLOUD was a Planet, it might be a space station of some sort.
The planet where they pick up Elnor and see the Romulan Refugees seemed to be a different place.
