Ainz undead domination

The taller robed figure extended a hand.
It was a skeletal hand.
The names of many skeletal magic casters flashed through his mind, but they
were all oddballs. None of them could have defeated Kunivela the Night Lich. So
what was this being — as his thoughts reached that point, they froze.
He had been dominated.
He could not even resist it.
Kunivela the Night Lich had actually been dominated like a Zombie or a
Skeleton. His mind and soul had already acknowledged the being before him as
his controller — his Master. What should have been an object of fear had become
a Master to whom he owed his loyalty.
He could tell that this was a skill to dominate the undead, one which he
possessed as well. However, that skill was only effective on undead weaker than
himself — which meant that his Master was significantly more powerful than
Kunivela. Once under his dominion, Kunivela would have no chance to shake it
off so long as the other party did not want to relinquish control. All that was left
now was to beg him — his Master — to show mercy.
