The Levites, the oldest and most powerful dragons in the cosmos, were six pillars of their race's cosmic power and influence.
They have been the deterrent that kept other races of similar power and cosmic powers from waging reckless wars or trespassing into dragon territory. They have also been the greatest of teachers, raising and mentoring millions of Ancient and Elder-Breed dragons.
Their fame and accomplishments were so vast that even after a billion years of total inactivity, they had not faded into obscurity, remaining well-known and highly regarded across the cosmic stage.
It's little wonder, then, that the few Progenitors who knew that the Progenitor Dragon, Aleksas, had no idea where they were, react with pure shock, unable to believe he could lose track of such powerful members of his race.
But then they hear the full story and realise Aleksas never truly lost track of them at all. Rather, the Levites themselves had chosen to vanish.
