Supernatural Territory, In front of the Vampire King's Castle.
About a thousand armed Vampires are lining up neatly in front of the castle with stern expressions waiting without moving a muscle, they are wearing a different kind of uniform than the Vampire's army which wears armor made of steel.
This army is wearing black thin clothes that grip their bodies tightly with a black hoodless robe outer that hides their body from top to bottom exposing only their head and shoes, their presence seems to absorb the light as their red eyes glow brightly. Black fur also surrounded their necks with blood red breastplates on their chests with a skull symbol in the middle.
Each one of them is standing under the sunlight without any hint of pain or disturbance.
Despite Vampires having an innate weakness against the sunlight this army of Vampires doesn't seem to be disturbed by it, there's a glowing red ring on each of them that protected them from the sunlight.
