Their appearance was horrifying. Their heads looked like human faces forcibly transplanted onto bat skulls. Pale and bloodless like a corpse, their skin was stretched tight, with blue veins visible like thin threads over their faces.

When they opened their mouths, their cheeks split apart, revealing hundreds of razor-sharp teeth. Their tongues, forked like a snake’s, dripped with black saliva that fell incessantly from their tips.

Instead of hair, they had writhing tendrils sprouting from their heads, moving as if alive. Their torsos were grotesquely elongated, a fusion of a human upper body with the lower half of a bat. Bones jutted out from their ribcages, piercing through the skin.

There were so many of them, they seemed to form their own forest. With their ability to fly, they swarmed quickly and latched onto the soldiers. Their enormous size gave them tremendous strength, allowing them to devour their victims.

Even the hardened elite soldiers of the North, who rarely flinched at anything, grimaced at the sight of these monstrosities.

“Ugh... what are those things?”

“Worse than the Grex.”
