Four Magic Cores of Legends

Kyran was inwardly surprised that rather than referring to him as the Dragon Lord, The Emperor referred to him as someone possessing the Draconic Core. While it was true that the Dragon Lord possessed the Dragon Core, thus, it was not wrong for one to be referred to as such, Kyran could not shake the feeling that there was an underlying reason that prompted The Emperor to mention the Draconic core, rather than the title of the person possessing one entailed.

Then again, the Dragon Lord title might only be known in the Lower Realm, and someone from the Higher Realm, where Dragons still existed, and whom they had a Dragon King- oh, right, he was already called Dragon Emperor- calling someone from the Lower Realm Dragon Lord might be inappropriate.

The two titles seemed similar, to begin with.

Two beings with similar titles could be confusing, even if they were from different realms.
