Hadrian Armored Legion

Originating from the planet Hadrian within the Jugen Sector they represent the sole product of the planet. Producing a regiment annually has lead to the Hadrian Armored Legion being one of the more numerous armored regiments within the Segmentum Tempestus. Renowned for both their close relationship with the Mechanicus as a necessity of maintenance of their mighty vehicles, and their mastery of the battlefield due to their tanks has lead to them being unpopular with other regiments.

Great Crusade
During the Emperor of Mankind's Great Crusade, the conquest of the Jugen Sector was handled by the legions of Leman Russ and Perterabo. When they encountered the planet Hadrian they found resistance fierce than expected as the planet was under the control of a mysterious Xenos Species dubbed the Nyk by Leman Russ. Believed to have originated from the Hell stars even the Astartes of the IV and VI legions were driven back for a time by the horrific warp-engines of the Nyk. However, such resistance could only last so long under the relentless pressure and elite skill of the Primarchs and their sons and soon the planet was under their control and the last of the Nyk retreated to their last bastion; the Hellstone tomb. Half in the warp, even the Primarchs were at a loss of how to destroy the tomb as it would reappear the next morning when destroyed.

After 20 days of unfruitful attempts to rid the planet of the Tomb, Perteabo declared that if they could not destroy it, then they would seal it away. As Leman Russ left to continue the conquest Perterabo would lead the construction of several mighty battlements meant to prevent anything from entering or leaving the Tomb, the mightiest of which is the Ring of Granite, a massive wall of granite surrounding nearly 200 square miles of land around the tomb. The human settlers were left with strict instructions to maintain the guard on the Tomb lest the Nyk return to retake the planet. A few Iron Warriors were left to teach the Human settlers how to maintain the defenses and how to manufacturer the weapons and ammunition they would need.

The Horus Heresy
When the Horus Heresy started, one of the targets attacked by the Iron Warriors was the Planet Hadrian. With a new knowledge of what existed in the warp, and of the true nature of the Hellstone tomb, Perterabo sought to reagain access to it to use as one more tool of war. Opposing the Iron warriors was a force of Space Wolves, sent by their Primarch who also remembered the Tomb. While the fighting would last several days, only the last was considered decisive. On the last day the two forces clashed on the surface of the planet, destroying many of the protections built by Perterabo before the Space Wolves finally forced the Iron Warriors from the planet. By the end of the battles, only the Ring of Granite remained to contain the horrors leaking out of the Hellstone Tomb.

The Ring of Granite
For ten thousand years the lives of the Inhabitants of Hadrian have centered around maintaining the Ring of Granite. The Wall itself stands 40 meters tall and is rumored to go as deep as 20 meters under the ground. All along the wall are carved battlements, gun emplacements, and an internal network of halls. All along the 8 miles of wall are thousands of guns, ranging from mighty artillery pieces transported by a wall top rail system, to heavy stubbers. While laser weapons are to be found the inhabitants of the planet have a noted preference for ballistic weaponry.

At random intervals attacks of strange creatures, often bearing little resemblance to the original Nyk, will assail the Ring. Such instances have been known to vary greatly with both scale and regularity. Sometimes months will go by between attacks, or sometime a whole year will go by as a single long battle. Sometimes the attacks will be a stealthy attempt to bomb the wall to break it, or be a full scaled attack at all eight miles of the ring. Examinations of the creatures corpses as well as their weaponry has lead to the theory that they are descendants of the last remaining Nyk, mutated by their long exposure to the warp.
