Enter the New Era
The souls of Krysta's parents were preserved and concealed within a soul gem. This preserved the body and locked the soul that was trying to flee.
But now, that crystal was broken! The souls had moved out.
And so, Nightwing used Unholy light to guide the parents' souls back toward the body. The souls thought it was already moving to a better place but were actually traveling a circuit that led back to the body.
And then Nightwing activated a certain power he had somehow known in his memories.
Somatos Ous Thanatou, the body of death, was activated.
The decaying and deathly power was so much that Nightwing's cultivation dropped by one level upon casting!
The bodies of Krysta's parents received the power of Somatos Ous Thanatou, which was focused on a certain spell that only Cherubims and Celestials could perform.
"[Anima]?!" The necromancer cardinal shouted in shock.
"What's [Anima]?" Ikarod asked.
