Getting rid of all problems
Although those from the tenth family were fighting well with all the support they were getting, they were nevertheless struggling to hold the line against the sheer number of vampires the eighth family had brought that day. Those with the shadow ability stayed a little further back and were using the shadows as best as they could to limit the number of injuries their family members received.
When one was badly hurt, some members like Dennis would carry them off, and enter the castle, closing the doors once again to keep them behind. They were trying to keep the deaths to a minimum, and luckily vampires were quite resistant when it came to dying.
However, there were too many vampires on the eighth side and eventually the eighth family got through. Even with the door closed, they began to scale the wall. They didn't know the special code needed to access the castle, so they decided to try entering through the windows and such on the floor above.
