Graanshoof is the smallest island located at the northernmost tip of the Hooper Chain, which used to be a part of the Maritime Stratocracy of Guantil-ya and its later forms until the Age of Gears and Elements. Because it lies barely above sea-level and often subject to storms, its inhabitants had to build dykes around its shores and many modern dyke building techniques originated here.
Every spring, when the sky-blue hillies begin to bloom on the dykes of Graanshoof, the yearly dyke race begins. Horse riders in search for glory mount their steeds and ride atop the great dyke of Graanshoof, which goes around the entire island. Once they are done, a spring celebration is held and the winner greatly honored. The race has its historic roots in the riders who protected the island by circumnavigating it along the dykes to check for weak spots that were in need of repair; they were… the dyke riders.
