Cartwright’s Cavaliers, one of the legendary Four Horsemen of Earth, have spent years rebuilding themselves to their former glory. Their commander, Jim Cartwright, has also been fortifying Earth’s military so it wouldn’t fall prey to alien invasion again, like it did during the Omega War. But unfortunately, galactic events won’t leave Jim alone. After an attempt on his life which nearly costs him his wife and children, Jim decides it’s time to face the unknown. He will lead an expedition into the 4th Arm of the galaxy and venture into territory nobody has explored for untold eons. Long rumored to be the hiding place of the Kahraman, the Cavaliers will go off the map, where “here their be dragons.” What awaits him there, though, is not what he expects, and he will be led further unto darkness.
