After travelling across the shadows, Thomas arrived at the nearest demon clan. A small clan of a hundred demons, the strongest in there being only a single demon lord.
This clan lived in a complex of numerous buildings, all of which used Cursed Bloodrock for the walls, pillars and everything else.
From far away, Thomas send his senses into the main building and saw a tall and ugly creature with gray skin, pointy teeth and long coiling ears. From the intense bloody stench stuck on him as well an strong baleful aura, Thomas was sure this was the expert he felt.
"That is the demon lord, he's almost losing himself to the aura of sin. Great, he's exactly what I need." With but a though, Thomas dived into the shadows down bellow vanishing from sight.
The demon lord in question was in his bed chambers with two low-rank fox demons. The two fox demons, a female and a male fox-eared demon were tied to the sides of the bed and blindfolded as the demon lord laughed heartily.
"Haha, look at what my boys brought for me, this is going to be a fun night." Said the demon lord with a lewd smile as he waved the whip in his hands.
"I don't care what sort of kinky shit you are into, but I will need your soul"
A voice suddenly echoed inside the Demon Lord's private chambers, the lord turned around instantly and yet couldn't find a trace of the owner of the voice.
The voice spoke again, now with a tone of satire. "Hey, I'm down here."
The demon lord's gaze move downwards only to see a fair, white hand emerge from his own shadow and grab at his neck.
Before the nameless demon lord had the chance to fight back, a earthshaking voice echoed deep within his mind.
His mind and spirit dwindled as his previously lived eyes went blank and fell onto the floor. Now, other than the two fox demon, a tall young man stood in the chamber. Still analyzing the images in his mind.
Shortly after, Thomas threw a quick glance at the two fox demon and waved his hand. Two white talismans shot out of his sleeves, hitting the two demons in the forehead before transporting them back to the place from where they had been taken.
Now, all alone by himself, Thomas gaze went to his hands then to the window, watching a giant moon in the sky. "As expected, Soul Devour is not hard when I have this new heart of mine.
Thomas took last glance at Ak'pi, the demon lord's corpse and sighed in his heart.
By now, Thomas familiarized himself with the current state of the demon realm. While the four dominions are still intact, he found out the structure within these dominions had become a lot different from what he learned from Kez'ganak.
"Kez, looks like this sector of the moon demons has changed hands. It's now under a new clan who changed it's name to Violet Moon Sector. A lot of old clans disappeared and others took their place as well. Currently, it's said the experts of the demon domain achieved the astounding number of fourteen thousand emperors. The threat is even greater than I have thought."
[....]
Kez kept silent but Thomas knew what he must be thinking and so he followed. "From what I heard, this current sector ruler does seem to have a deep hatred against the Sonad Family, with both sides fighting each other behind the scenes. And another thing is that the Violet Moon Empress not only is very young as possess an expectational physique that enables her to cover her entire body in violet scales and the symbol of a crescent moon appearing over her head."
[Wait, are you saying...]
"While what I saw in that demon lord's memories are only rumors. I believe that is some truth to it. If so, then this empress must be connected to your clan, maybe she's even your long lost sister."
Inside the system space, Kez entered in deep thought. During his entire time in the demon realm, he barely came to know anything of what came to be of his sister. He even suspected she died along with the clan, and at that instant his spirit burned with excitement.
After a moment, he coughed a little before asking quietly. [Thomas, could you please check if this Violet Moon Empress is really my sister. While my powers are insignificant to you who possess this overpowered system, I really hope you can do this for me. For once I find my sister, I'll be finally free of worries and ready to pass on the little I have to you.]
[Fallen Demon Lord's Final Quest: Reunion of brother and sister.
Description: Help Kez'Ganak find his long lost sister.
Time Limit: None
Rewards: Infernal City]
Seeing the window pop up, Thomas was surprised by it's contents. It turned out even for Kez who is not a deity, there's still a final quest. But in his case, the rewards wasn't anything Divinity or Faith.
Instead, it was the system that decided another reward for him. But, a city? Why is his rewards for completing his last quest be a city? Does he even have a use for a city?
While he was unsure of the reward, Thomas accepted the request anyway. For him, there's no way a reward for completing a final quest be something bad.
