(September 2012)
From the game, Amnesia: The Dark Descent. The Kaernk is an invisible water-dwelling creature that trained me to be terrified shallow pools of water.
Since there's no official art for the creature, it can't hurt for me to take a shot at it, right? I imagine it spends most of its time waiting for some unfortunate person to unwittingly step into its invisible bear-trap of a mouth-thing.
