"Transylvania 1887" from Van Helsing.
Part 9: I Bid you Welcome
Shaggy, Scooby, and Velma blinked the light out of their eyes as the school faded away and a new locale was thrown into sharp relief. Leafless trees shook in the rain and howling wind. The sky was inky black. They were somewhere high up, at the peak of a mountain. Below they could see lights, a village maybe.
But in front of them was the most terrifying sight of all. It loomed high into the clouds. Great towers ended in pointed spires that seemed to beckon the lighting towards them. The wind whipped through the stonework creating the most excruciating sounds imaginable. Right in front of them was a set of massive wooden doors. Above the doors there were words inscribed; Abandon hope all who enter, and prepare to pay him tribute, for you are at the house of the Dragon's Son.
The doors swung open and the three of them were pushed inside by the barrels of guns. Griffin had shed the last of his facial coverings and was now spreading his arms in a welcoming gesture as he led the way inside.
Standing just within the doors was a man who seemed to not be a man. His body was lean and he stood arching forward in a way that should not have been possible. His black hair was slick and hung down the sides of his face, coming to a sharp widow's peak atop his forehead. A thick black mustache and beard adorned his pointed chin. Angular eyebrows formed a V above severe red eyes. Down the right side of his face and across his right eye there was a long red scar. Blood red lips curved into a saccharine smile that barely revealed white, needle like, fangs.
Shaggy and Velma were forced to their knees in front of him. Scooby bared his teeth for a moment and in return the creature bared his, silencing him. He smiled down at Shaggy and held out his hand, sweeping it across the room.
"I bid you welcome" He said in a smooth eastern European accent. "Enter freely and of your will. I am your new host and master. I am Count Dracula."
