Walkthrough: North of Route 13 is the Haina Desert, a massive maze that eventually leads to the Ruins of Abundance, containing nothing but Items and Wild Pokemon. The navigation of the desert is done by each exit with each area having a set number of rocks. To get through to the Ruins of Abundance, you need to follow the rock paths of 2-1-4-3; however, the paths will not return you to the same part you entered from.
