Noctua returned with a distrans decoder and delivered Zantara's last bittersweet message, addressed to me, now intelligible: he tells me of the ominous vision he had when he saved me from the wreckage, of the Sleeper and I both lying on the ground, and the Sleeper disappearing. He also reveals that the Fremen still live, as I suspected, and that they are hiding in the southern hemisphere. For now however, I do not have the means to find them. My mission continues.
