Following the instructions of Elara Tuek, I slipped into the mansion of a Water Shipper outside Arrakeen. I poisoned his water supply - but before I could escape he confronted me. He told me that he understood that I had been sent to check on him, but that his plan to find the fremen was almost complete. When he drank the water and died, he begged me to save him and hinted that he knew a way around the compulsion...but it was too late.
