Chronos

Lore
Chronos is the initiator of the humanity's dark age... He consumed all the angels because he could get more power of them...

He was nearly unstoppable,.

Zeus, a powerless angel, was never absorbed by him because he was too weak, but that was his highest mistake. The angel trained for centuries until he managed to steal the relic of knowledge from Chronos and start a war against him. With the relic, he created the Tree of Life as a plan B in the case of he died during the war against Chronos, so he could train on the underworld until the time he could finally beat Chronos, but he never use it because he finally defeat The Destruction by sealing him into the space-time relic.

From that day on, we never heard from him again... Until a possible release?
