As he rose to his feet he discovered something that filled him with true fear. The blood was getting deep, deeper than the room should have allowed. It was as if the blood had created a lake, deep and unfathomable.
As he realised this he felt hands grasp his ankles and pull him down. A cry was choked off as the blood entered his mouth.
Other hands joined the first, clawing at his body now sodden with blood. Hands that dragged him further and further under the surface no matter how hard he fought to survive. As he went under he saw dim, dark figures holding him in their embrace. No one would ever find his remains, he would rest here with them forever...
As his last bubbles of air rose to the surface of the blood there was a chuckle, Death himself had come to claim the last of the line. Death allowed those trapped here to exact their revenge on the house and all those within it.
