Secret Techniques

At the end of the day, Nial didn't reveal the full powers of his Golden Eye.

He said that he could enhance his Silver Eyes to a small extent, but that was it.

It was not as if Nial didn't trust the others, but he didn't feel like telling anyone about his hue of potential ability.

Even if he was the Crown Prince, he didn't want others to find out about the ability. Others would want to abuse it, that was for sure. 

However, that was not all. 

The Creatoran race would start depending on his ability to discern 'useful' familiars from 'useless' familiars. Maybe not all Creatoran would try to make use of his ability, but the turmoil revolving around him would grow even worse.
