Ereshkigal was still bewildered by Annanu suddenly turning into Enkidu when Annanu appeared in the sky an instant later.
The Key of Heaven's suppressive power truly was inferior to the Chains of Heaven.
Wouldn't it be fine to just switch the Key of Heaven for the Chains of Heaven? It wasn't as if they couldn't switch back afterward.
Annanu and Enkidu had been summoned as a pair. In a Singularity like this, as long as one of the two brothers appeared, the other would naturally appear as well.
Annanu had sensed that Enkidu had been summoned into the skies above Mesopotamia, which was why he chose to switch with Enkidu.
They had originally been one entity. As Servants, they could switch bodies through their shared nature. In any case, both bodies were molded from clay, so it made no difference who used which one.
Floating in the sky, Annanu glanced around, his expression turning grave.
"Mother Goddess, you really have awakened."
The direction he gazed toward was the sea.
By the names of later ages, that place should have been called—the "Persian Gulf."
The surface of the Persian Gulf looked calm and peaceful, but Annanu knew it was not that simple.
He could sense all energy converging toward a single point.
Something had awakened long ago, but its true form had yet to fully reveal itself.
"Enkidu, are you done?"
Annanu asked Enkidu through their souls.
"Wait a moment. I'll be done soon."
Rattle—
In the Underworld, Enkidu raised both hands. Countless chains surged forth, wrapping layer after layer around the giant beast. With the support of the Key of Heaven Annanu had left behind earlier, they finally completely suppressed the giant beast that still wanted to struggle.
"Good, this should do it." Enkidu let out a breath of relief.
