The life of the son of Dracula

A man has fallen into a dark ancient ruin. He turns on hit helmet light so he can see. He sees an ancient monolith. He touches it and it opens with a rotted corpse inside. Suddenly the corpse was not dead like he thought it was. The corpse grabbed the man and wrapped its wmrotted wings around him and bit his shoulder. The man let out a blood curdling scream, but nobody would hear him. the corpse sucked the man dry then put him in the monolith and closed it. The corpse turned into a young man. That man walked outside the ruin. He looked towards the north and said " I'm coming for you." He walked to a small town full of castaways. He found refuge there...and food.
