Long in the past there were still countries that still resisted his rule, he didnt mind they would succumb to his might and guardians sooner or later, the worst offender was the slain theocracy, he paid them little mind though, once they were a thriving nation but now is an isolated patch of land, locked away from the World that surrounded them, since they refuse to fall his all-mighty word of law, he would have let them whither and fall to history or to his rule, that was until they decided to strike out and harm is family, they had used a world level item to kill Shalltear.
The ancient ruler's eyes drifted to the right, his eyes finally settling on the ageless beauty, with flawless porcelain skin and an air of confidence no one could deny, her eyes lifted to meet Ainz, her soft voice echoing out "is there something the matter my Lord?" how he wished he said no ... how he wished he had gone himself or a mere minion to scout the area out fully, there were so many things he could have done ... would have done if he knew how this would have ended, but hindsight it 20/20.
there had been whispers of rebellion from the old guard of the slain theocrasy, with nothing concrete he wanted to send someone to see if the whispers were true, but having lots guardians and maids thought the years he was reluctant, until Shalltear had knocked and entered his office looking for her next task, Shalltear was one of the strongest npcs in Nazarick and she's undead surely, she would be safe to send, he remembers telling himself knowing he couldn't let these rumours go unchecked.
Unfortunately, that is what the slain theocrasy was hoping he would do they had been waiting for her, gathering what remains of the scriptures with hero's and items, while strong Shalltear knew she could take them. she donned her crimson armour and pipet lance and readied herself for an attack, when none came her stance loosened, tentatively "what, the poor little humans scared? gathering in secret to discuss plans that are doomed to fail?" gigging to herself as he taunted the group of humans, their faces a mix of fear and anticipation, Ainz sitting on his throne watching the altercation unfold from the mirror of remote viewing, he felt a strange sensation like a shiver down his back, something felt wrong, what was it ... the ones in front? Weak to Nazarick but fairly strong for this world but they are grouped around one .. They seem to be protecting her .. but why her?
