It would be good if Worf trained Harry.
I would like Harry once back on Earth to find some of his friends descendants, like, Luna, Hermione, Delacors, Weasleys, Dobby, Griphook, Etc.
I hope Hogwarts is still standing.
I hope Gringotts is still standing and Harry has loads of thangs still there.
Great story I am looking for more.

Unfortunately, Worf isn't even alive yet, and the Klingon family is a different one than Worf's (different pronunciation and slightly different spelling of the name. Kinda Like the Last Names of Nielsen and Nielson. slightly different spelling and pronunciation.) Hogwarts is still standing and Gringotts is still there as well, but not in the manor that you may be thinking. Harry will be finding out what happened in due time, but for now he's going to have Lots of questions but very few answers for a few chapters yet.
