Regnum The 5th Age
This lush jungle and marsh land area was left alone for thousands of years known by sailors as the Dragon's Arm and by the scholars and educated as the Isthmus of Drakkos. Drakkos was a powerful fire dragon whose scales were often mistaken for burnt rocks due to extreme age. The appeal for this area becoming a Dragons paradise is due to a ley line with multiple nexus points (where two ley lines cross) runs from southern Sussuria through the entire Isthmus and 250 miles out into the ocean past the Free Islands. A humanoid serpentine hybrid race calling themselves Dragonborn showed up around 6,000 years ago and were seeking refuge from the world of the Founder Races. The ancient Fire Dragon, Drakkos, struck a deal with the Dragonborn called "Yin" to convert to Dragonwright and they would be given haven among the new nation of Yin-Drakkos. The land is one of the most well-preserved natural environments in the world with every city taking extreme measures to ensure minimal impact on the environment. Many consider the Isthmus to be among the most beautiful jungle, wetlands they have ever seen.
