The termination thread reminded me of how that word has always bugged me. It suggests being fired and/or death. As opposed to the end of a journey, which is what I think it was originally supposed to indicate in the context.

I put up a poll for possible alternatives, drawn from the thesaurus, but what do you think of the word/what would you substitute and why?

I like the Greek word telos myself, it means that one's object has been achieved or completed.
