Great Roc Wing Beat, A Pale Blue Hand
Izroth observed the ancient roc summoned by Aurelius. While its presence was nowhere close to that of an ancient beast, the pressure it gave off was enough to fool most and cause them to retreat.
Of course, what Aurelius called forth was not a genuine beast. The ancient roc itself was formed out of sword intent, as well as the Law of Wind and the Law of Lightning.
Earlier, Izroth detected faint traces of the Law of Wind from Aurelius' sword; however, it was the first time he had witnessed the Law of Lightning.
To most, it was common knowledge that a person or object could only contain a single law of the world. But that was not always the case.
For example, thanks to his skill, The Unbounded One, Izroth was able to comprehend not only the Law of Void but the Law of Causality as well.
That being said, Izroth's case was one of the utmost extreme rarity.
