Overlord x DOOM

Samuel

As Ainz walked backed to his throne, he realized a couple of eyes were staring at him in a doubtful manner, though Ainz knew who it was he turned back to question that person.

"What is it Warrior Chief?", Ainz asked  curiously. 

The slayer did not say anything, there was an awkward silence for some time,

"Shit, did Samuel betray us?!", Ainz thought.

The silence was broken by Samuel who informed the Slayer that while he was away, they were discussing about the hell demons and about how he and the slayer should visit the other floor's of Nazarick.

The slayer looked at Samuel and then looked at Demiurge with a murderous glare.

Demiurge shrugged the glare off and walked towards the Slayer, " So Warrior Chief, Samuel which floor would you like to visit?", Demiurge asked the two of them.

The slayer looked at Samuel, "This will be interesting Slayer," Samuel spoke.

'This is odd, Samuel is persuading me to join' the slayer thought.

'Why is it that Demiurge  is asking?', such questions filled the Slayer's mind.

Samuel noticed that the slayer was in deep thought and quickly changed the subject.

"N-now about the Deadborne", Samuel spoke.

"Yes, how did it enter into our world?", Albedo questioned.

"Coul-Could there be an invasion?", Mare asked.

"That is my worry Mare, though we need to also know why it appeared near the village of all places." Ainz replied.

Deep thought's filled the room.

Samuel knew the reason, he just wanted to see if anyone could come up with anything, in particular Demiurge.

"There is only one way", Samuel spoke out.

"What might that be?, Samuel", Ainz asked.

Everyone looked at the white object as Ainz asked the question.

"During our adventure to save Earth we entered a realm known as Urdak, that realm was governed by a being known as the Khan Makyr. In an attempt to destroy Earth, the Khan Makyr tried to control an ancient evil known as the 'icon of sin', the slayer did not allow the Makyr's to control it and as a result a holy seal, that was meant to protect Urdak from Hell's forces had been breached allowing the demons to enter like never before -", Samuel told.

"I am very sorry to interject but may I please ask a question?", Lupisregina asked.

The battle maids Yuri and Narberal instinctively punched the back of her head without warning.

"What?, I asked!", she responded.

"It is alright you may ask, but please the two of you should look at your surroundings, before you hit your sister", Ainz told.

"You need not worry Lord Ainz, I will deal with them myself", Albedo responded.

"If the seal had been broken, shouldn't the warrior chief have fixed that before he went to Earth?",  Lupisregina asked.

"Even if we at that time had the means to reseal it we couldn't take the chances to let the 'icon of sin' roam the Earth freely, for the longer the icon of sin is on Earth the stronger it would become, that is why the icon of sin was the primary objective and once the slayer defeated the Titan, our next objective was to seal the void in Urdak, Urdak is a realm beyond reality, beings from Urdak can easily travel to known or unknown worlds. This would mean that the Demons are either going through the void to random world's and establishing their dominance or they are trying to get rid of the Slayer before he causes more trouble for them." Samuel replied.
