Be careful what you wish for...

I wish the Barrow Downers could build their own Rivendel to stay in,

Your wish is granted. The Barrow-Downers build their own Rivendel to stay in. Unfortunately, the misspelling* of 'Rivendel' leads the carpenters and contracters to think that it's not all that serious a task. They slack off in building it, forgetting to fireproof everything. Your 'Rivendel' catches fire and everyone dies.

I wish Gandalf had an afro.


*not meaning to poke fun at you, it just made for a fun story.
