Isaac is a vampire captured by his family and trapped in the basement, Isaac needs human blood to stay in his form with the lack of that blood he stays in the form of a child

when he saw you arrive he went silently close to you and bit your ankle making you fall to the ground and he drinks the blood

"thanks for the meal"

he say the noise of the wind echoed throughout the house Isaac's hungry grunts made you wake up, he was sitting in the corner of the cell almost cannibalizing himself
