Overlord The Son of Death

The Knowledge of a true Heir

 All of the people who entered quickly kneed and bowed to their leaders and superiors, Ainz looked at them and there was a sudden red glow in his eyes. "State your report", ordered Ainz.

"Yes, Lord", the members of the trailing team said in unison.

One of the Vampire Brides spoke, "Lord after you assigned us our mission, we trailed Sebas's and Shaltears carriage. Once they separated routes our team split as well, our group was the one who encountered the incident."

"What happened?", Ainz asked.

"Once Lady Shalltear encountered the adventurers she headed into a cave further in the mountain. Once she was there we made sure to be at an area where we couldn't be exposed. That is where we saw them, two different groups. One of them was a simple adventure group, they were called by a man that had managed to survive Shalltears assault. The second group was different, they seemed like a group of special warriors", she said.

"Please explain in detail", Filius asked.

"Yes Lord, these people wore high-level equipment, some wore special armor and robes, they contained special powers and abilities. Then once Shalltear noticed that she missed one person from the men she attacked she sent her household to scout, this group of warriors instantly killed her summons. Then she went to attack this group herself, the group tried attacking her, but they failed. Shalltear managed to kill two of them but the rest still lived, Lady Shalltear then stood there in place staring at the floor", the Vampire Bride said.

"What happened to this group?", ordered Ainz.

"Nothing, they retreated once their comrades were killed after that Lady Shalltear was still stuck there", she said.

"Hmm, probably they tried using some sort of mind control", Filius said as he looked at his father.

"Yes, but what the real question is, why did they leave her there?", Albedo asked.

Filius quickly formed an idea, he then turned to the Vampire Bride, "Who was the one who casted magic or attacked Shalltear first? Were they still alive or were they killed by Shalltear?"

The Vampire Bride nodded, "Yes, the humans that attacked Lady  Shalltear were killed, except for one man. Though this human didn't use any magic, the only other human who used magic was killed by Lady Shalltear."

Filius quickly formed the connection and turned to Albedo, "Now I see. It may be that the magic user was killed before she could fully control Shalltear. So they left knowing that they couldn't do anything leaving her in an independent state."

"Yes, Young Lord, your theory is the most likely", Albedo said.

"So that means that Shalltear isn't fully controlled but also that she isn't under our control", Ainz said, [Thats a problem.]  He then turned to the screen in front of him, [They have a point. If we were still in Yggdrasil, this status marker would indicate that a third party had used mind control magic and temporarily turned our NPC into an enemy. Though that should be impossible since Shalltear is undead. Also, she has a skill that nullifies all forms of mind control instantly. But if it were a special mind control spell, skill, or ability that can work regardless of any preventive measures then that is something else.] He then turned to Filius, "Son, from what we've gathered, there are talents and martial arts in this world that did not exist in Yggdrasil. Which of the latter do you think was?"

"If I may speak freely, Father?", Filius asked

Ainz nodded, "Yes, speak."

"Father, I believe that if someone was able to take control or mess with the free will of someone like Shalltear with her skills we should consider it a high-level skill or a World level Item. It isn't paranoid to be cautious", Filius stated.
