To access this quest, the previous quest, Crusaders, must be completed.
Vein recognizes the leader of the crusaders, even if they are just a local border guard patrol. Apparently, they have been securing the path for a prince of the Lotus Empire. Interestingly, the prince and his guards, the Sayamas, claimed the Sahaar desert as their own, being the dune nagas. They charged on the group, moving through the sand as if it were the Jade Sea itself.
