- Hadrian is the name of a Roman emperor who ruled from 117 to 138. His most famous accomplishment is the building of Hadrian's Wall in Britannia. He was known to spend much of his time with the military, even dining and sleeping amongst them. He increased military training and used false reports of attack to keep the army alert. These details may have inspired the effects of Hadrian's Crystal: The increased attack and polearm skill represents military training and the reduced damage represents the wall.
