Rezhn in linear North America, stretching across linear Gulf of Mexico, from roughly Veracruz, Mexico to San Cristobal, Cuba. An extreme rezhn consisting of what we call the ocean floor in the Gulf of Mexico—the Sigsbee deep. According to legend it was perfectly flat (recent research shows it is not exactly true) and the popular game known as the Klurrulurrudur is played on a vast flat surface named for this rezhn.  Also: the original Tagans are believed to have come from here. What we call the Sigsbee Deep (part of the Gulf of Mexico).
