Isaac was lost. He had messed up on the map he had been drawing and was now wandering around where he thought might be somewhere in the middle of the maze of rooms. He stumbled upon a room in which he had not been. After flinging his tears around for a couple of minutes, destroying the frail bodies of the monsters, he finally finished off the last one. As it crumpled into dust, a huge door swing open, shrouded in bones and glowing with red light, Isaac knew that he had found a different room. Something behind it was strong.
