No, sorry. Also sorry it took so long to reply, I woke up late and didn't have time to check this morning before work...
Well, I think this last line will make it a giveaway, so I'm only going to give the first word of it. (I'd rewrite and extend it, but I'm also afraid I won't be able to make two more lines that both fit and rhyme....)
But I will also give another clue: the wording of the first line is very deliberate. Notice, it doesn't say "combine IN me," but "combine BY me." (And I don't mean as in "nearby," either.)
See if this makes any more sense now:
"All four elements combine by me,
Though one in my hands is all you'll see;
After the end but before the fall...
