Find the Sealed Box and then deliver it to Earthbinder Tavgren just outside of the Cenarion Thicket in Terokkar Forest.
You know, come to think of it, I do recall selling several boxes of strange and exotic engineering parts to Empoor about a month ago. I'm not sure what they'd be used for, but I know that they were delivered to Tuurem.
Perhaps one or more of those boxes is still there?
