He examined the streets of Northwatch, looking through the crowds of people. The occasional guard passed but payed no heed. Many men had hoods up, and faces down. A few women. His blood red eyes scanned people. Some Thanati citizens might recognise him. Or they didn't know. He found a food stall, paid for some bread, and continued on his way. Eventually he became bored. He looked at the sky, and saw the suns position. He tried to remember where the graveyard was. When night fell he would set to work animating skeletons and zombies for a warm up. Then possibly summon some spirits to haunt the area. He felt mischievous and summoning the dead was fun.
Night set in, and he walked to the graveyard. No one stopped him. No one questioned him. He liked this town. Maybe when he retired he would settle here. Or he could simply overrun the town with zombies. That would be more fun. He noticed the man in the graveyard was tending to the grounds. Why did he have to be there?! He would simply kill the man if needs be. Then he remembered his promise to Nadya. No killing unless they posed a massive threat. This groundskeeper did not fit the bill in his humane eyes.
Instead he took the hilt of his knife, walked up to the man, and took a massive swing at his head. The man crumpled under the blow, but silently he went. He took the mans body and dragged it behind the tomb, in the shade of a bush and headstone. He checked the mans pulse, and tied and gagged him. Didn't want him getting up. He took a minute to make himself presentable. He found a suitably damaged and unloved headstone. The flowers were, by his reckoning, at least a year old. He doubted anyone would care.
He needed no book to summon the zombie. He summoned the energy, spoke the rather longwinded incantation for an undead warrior. He waited to hear the pounding and scratching of a flesh hungry zombie. It eventually clawed its way to the surface, and he stroked the skull. His new friend was gonna be this skeleton. It would keep him company. He just hoped no one else was going to be in the graveyard tonight.
