The darkness was running through the realms while trying to search for one that still had his body around it.
But Kosma had been quick in her job and had removed all of the clouds from almost all of the realms. The only remaining realm was the spirit realm where the elemental rulers were.
Since the place was divided into numerous sections, Kosma had to personally enter all of them and remove the parts of darkness. But before she could remove it from Levina and Mariel's domain, the Darkness appeared there.
"You look… exhausted." Kosma looked surprised as she the darkness's bloodshot eyes.
He was eyeing the blue spirit realm behind her with a desperate look as though it was his last chance.
Kai also appeared there moments later as he had gone to all of the realms the darkness had been roaming around.
But now, it was the end for him.
