The Immortal Shadows.
Spurt!
The vines sharply speared through Isaac's legs and pulled him out of the tree. Soon after, his back was thrown up against some hard ground and dragged inside a cloud of black smoke.
"N-No!" Isaac tried to rip the vines, but only his hands got riddled with wounds as a result of this.
Soon, he was engulfed in the black smoke, and an endless coldness began to seep through his bones. He started feeling a strange kind of terror in the depths of his heart.
The whole thing felt as if he had been dragged into a cave of an ancient beast where he was the prey for the day. The terror came from wanting to live and not get eaten by some terrifying beast.
When a number of figures appeared at the forefront of the black smoke, the terror became more intense. They were clad in the black smoke armory, holding dark-bladed swords.
They were the shadowy figures whom Isaac had assumed to be responsible for the creation of the mysterious black smoke.
