Attack Power of the Dragon
The main weapon of the dragon is lightning shot from its mouth. Its lightning has the odd trait of bending towards its target. There are also reports of homing bullets and waves of living particles, but it’s all hearsay.
The dragon’s powers exceed any weapon we now possess. The Academy calculates that the dragon has the potential firepower of at least fifty gunships.
The Dragon Rider
The most notable report about the dragon is that there was a rider on its back. Besides a few lesser monsters, such as Coolias, no creatures exhibit fond behavior towards humans.
The identity of this rider remains a mystery, but his amazing reactions and advanced combat skills indicate he’s not human. Thus the Academy has theorized that he is a human-shaped creation, similar to the monsters.
The Dragon and the ‘Tower’
According to the ancient records, the dragon and the final weapon, the ‘Tower’, are linked somehow. Our researchers are split between the theories that the dragon is the Guardian of the Tower or that it is the destroyer of the Tower.
On Imperial Year 89, while the Empire attempted to reactivate a Tower, two dragons appeared, and acted in completely opposite manners. This created even more confusion over the dragons. All we can conclude is insufficient data.
