To be honest, the Plague Doctor shouldn't have been under the command of the Great Old One which has been sealed in an eternal state of limbo. He was more suited to the King of Monstrosities but the simple-minded monstrosities could not appreciate his value and were relegated to the Great Old One, the next suitable one to serve.
As soon as he was given the command, the Plague Doctor immediately went to work.
There were many animal corpses lying around the forest. Some had only bones while some still had some flesh in them. The Plague Doctor used parts of the dead and combined them with fresh organs of the living to create his first creation.
One-eyed Zombie Wolf-dog.
"Uh... It's a failed experiment. I should have prepared more flesh, the one-eyed idea is a complete downgrade and the bones don't allow for more advanced movements... Ay..."
The Plague Doctor sighed.
"Don't worry, it's okay." Angelo patted the doctor's shoulder, "It's good enough for now..."
"If you say so... Anyways, I will rest for now. Undead reanimation is too exhausting, next time, I'll do live experiments. It's easier, cleaner, and does not consume that much energy." The Plague Doctor nodded and disappeared into a black mist.
Waiting until the black mist evaporates, Angelo looked at the minions around and barked: "Did you hear what he said? You'd better bring him what he wants tomorrow!"
The black demon, floating skeleton, and flesh-human hurriedly nodded and immediately went to search body parts and suitable living animals for the experimentation.
"And you... follow me." Angelo said to the other spirits as he took the one-eyed wolf-dog.

Angelo stood at the boundary of Kusak village.
"This will be our first base of operation. For this, we need to corrupt them."
This village is so isolated from civilization that government officials do not even bother to interact with them. It was so unknown that most people living in neighboring towns and cities did not know that it existed.
This was an ideal place to make new believers.
He initially wanted to convert the habitants with Prophet's Command but Arianne's appearance changed his plan. Since he couldn't directly proselytize, Angelo decided to break them with fear.
First, it would this rotten wolf-dog. Then it would something bigger and stronger. Then more and more until the villagers would figure out the pattern and fear and despair at what is coming.
So, Angelo released the wolf-dog.
And the next day, he released a mangled black bear.
And the next day, he released a five-headed giant wolf. At the same, he put the spirits at work.
And the next day, he released a deformed long neck humanoid.
And finally, the next day, he released an Evil Eye.
The sheer stress and fear accumulated during the previous days broke down these humans which he used to dominate them with a lesser abhorrent charm.
Instantly, the remaining villagers who were broken from fear managed to find a light under the veil of darkness and desperately grasped their last straws and converted to the cult.
Seeing the obedient humans kneeling towards him, Angelo curled his lips.
Mortals are so easy to dominate.
