[Time Dragon Egg]: The egg of a Time Dragon, the leader of the Time Clan in the long river of time.
The Time Clan, full of terrifying existences with endless lifespans, coexisting and dying with the long river of time. Even if billions of worlds are shattered, the long river of time can still be eternal and flow toward the distant future.
However, in these tens of millions of years, an earth-shattering battle has once occurred. The Time Clan experienced defeat in that battle. While an unknown strangeness has occupied the long river of time since then, the rest fled to the origin world.
Alas, the origin world was destroyed, too, so the entire Time Clan perished. As the last hope of reviving the Time Clan, the dragon egg was transported into a vast and endless void.
