"This is it? A little thrill ride?"

Abaddon latched on the the side of one of the constructs, adrenaline rushing throughout his body as he and the other structures descended rapidly to the ground below. Arcane energy began to curl off of his body as Abaddon began to store up energy for what he was about to do.

"#This thing is basically a nuclear missile. Once it hits what's below-"
 
"I know, it goes kaboom and kills whatever poor suckers are down there. I got this!"

Abaddon raised his right claws, releasing a huge flash of purplish energy which enveloped him and the nuclear reactor. He took himself, the reactor, and whatever other debris he could to the dark realms, so at least now whatever damage would occur down below would be minimized significantly. 

The debris and reactor appeared in a different place of Gehenna at Abaddon's choosing, while he himself appeared on the pinnacle of the tower that formerly belonged to the dark entity that originally ruled from here before his realm was taken and merged to Abaddon's. 
Dropping to a knee, Abaddon rested. The whole transporting of himself, the reactor, and the debris had taken effort. His strength and energy quickly replenished, especially as Abaddon fed on the bodies of humans and other beings he had skewered here on top of the pinnacle's adorning spikes. 

"I'm guessing he's taken care of most of the Locust Swarm, huh? Unfortunately for him, that only made their essence disperse from their bodies and seep deeper throughout the energy flowing in his little 'kingdom'. Inadvertently, the swarm's work still continues-"

"#And it does so even quicker than before. What we have in store for him next-"

"Will basically seal the deal," Abaddon finished with a laugh. He held out his claws and produced a dark orb which showed what his opponent was doing. He was distracted. A good opportunity to strike, especially now that he thought Abaddon was still falling to the earth below. Abaddon's claws and tendrils sharpened and glowed with deteriorative magic as the orb flew in front of him and created a portal diagonally behind Kami. 

Leaping through the rift, Abaddon carried out his attack, raking his opponent with empowered his claws and tendrils before digging them all into his body and releasing a surge of harmful dark magic into him.

"Surprise," he mocked as he released Kami and let himself fall to the earth, landing with no damage. Abaddon prepared himself for a counterattack.
