In a random cave of the tomb.
There was a ball-shaped shadow twisting in the darkness.
The shadow moved on the floor like flowing water and it slowly stopped by the exit of the cave. The shadow started transforming and turned into a humanoid being several seconds later.
It was a man with a pale face and two balls of burning green flames in his eyes. The blue light from the glowing moss illuminated his face—it was Shadow Lich, he was the one who took the liquid in the pool.
The aggressiveness had already disappeared from Shadow Lich's face, he was checking the surroundings constantly, and it seemed like he was trying to stay away from someone.
