What is Two?

"Right, on that note," Sofiera chipped in, recalling that long ago she had promised Eldrian to help find two certain items. Up to now, she had little success. But the duke would have much more power. "He also requires a Magic Crystal and Lightstone."

"He requires what?!" The duke could not believe his ears, things like that were not some common items. The emergency Lightstone he had given Myropsis had taken him years to acquire. It was normally used in national-level things, not for personal matters. 

And the only reason he had managed was that he had promised to return the dust after use. Which was more useful than the stone itself. 

A Magic Crystal was even more so a national treasure. To gift it to a single person was not a logical action. Not even the king could decide to use a magic crystal casually. It was simply of too much importance. 

And with Sofiera's words, a shadow of worry started to grow in the duke's heart.
