Well, lucretia, it's not so much a secret passage as it is a safer way to reach the other end of a tunnel. I think the basic idea was this:
<span class='standouttext'>Spoiler : </span><span class='spoiler'>Entering in between torches 1 and 2, you are able to walk AROUND the trap, extinguish the torch along the way, thus opening up the trick wall at the end and continueing along the way to an illusionary door. Trying to open that door makes a skeleton mage and a treasure chest appear.</span>
