Wrong Way

Everything was black. Pitch black, as only caves can be.
How to find the way out? I can’t go back...
He didn’t remember why. Just knew. That way is shut. It was made by those who are dead and dead keep it.
He took the rope out of his backpack. The standard equipment. Couldn’t see it, but would recognize it everywhere.
He tied it on a stalactite and started exploring...
Couple hours later he finally saw light. The way out. The secret valley.
As he stepped out, defense mechanism activated. A cascade of strange tones sounded...
And everything went black.
