[The darkness was thick and suffocating, like a heavy blanket had been thrown on the world. He had to get over the wall, had to get across the border before] the dark seeped all the way into him. He could feel it in his lungs now, filling them so that every breath was a rasp. That was the sign that he had been in the dark for too long. But this time to find what he was looking for he had needed to go further, past the last post, only the tail of the rope strung along the posts to tell him how to get back. He had reached the end of that rope and let it go, stumbling into the dark several steps before he found the inkwort prickly against his fingertips. By that point he only had time to grab a few handfuls, and then he turned and hurried back, hand over hand along the rope.
