Your team of Fremen spies have infiltrated the bases of the three Houses shown on the Arrakis map. You may solve the open puzzles in any order. After solving a puzzle from one of the Houses, you will likely explore more of the base of that House, uncovering other open puzzles. You will need to uncover the secret weapons of each of the three Houses. These puzzles are metas, and use the answers from their corresponding House puzzles. There is a final meta-meta, which uses the answers from these three metas to help find your savior Mahdi.
