You were able to solve it, why, aren't you clever. But if you thought hint three was hard, four is not much better.
"Continue on, find me" was all it said, a clue like that just hurts my head. Unless, of course... you must add on to three, but to do that... you must add me.
Alas, I've searched this page up and down, and not a single link can be found. Now this is a puzzle, yes indeed... where in Yevon does this labyrinth lead.
My suggestion is to go back, as far as you can, retrace your tracks. Maybe then, with "sixteen, four, eleven", you may find the answer to this final question.
