The Island of Destiny

You grab hold of the vine and start to carefully edge your way down the cliff. After a few moments of climbing you see that this vine is taking you to a small opening in the cliff. It looks like a cave.

Since you're already this far down the vine you conclude that you might as well explore what's in there. But as you barely feel your feet touch the ground -snap- the vine breaks. Quickly you scramble to maintain your balance on the edge of the cliff. Luckily, you are able to.

Now you stand looking into a dark cave that you cannot see more than five feet into. Should you venture in?
