You run back to the fork in the road and head toward the castle.
On the way, you hear a whistle in your ear, then another, and then feel a sting just above your hip.
They do have bows!
The wound isn't bad. It's a small arrow, shot by a weakling, no doubt. You pull it out without losing stride.
After a minute of stumbling down what is best described as a game trail, you see the shadowy husk of the ruin in the moonlight ahead. Unfortunately, the battle cries of your pursuers are closer than ever, and when you look back over your shoulder, you see glowing eyes.
The two of you turn on a boost of speed, and soon the outer wall of the castle looms before you. It is about ten feet high and crumbling. You realize with horror that there are no holes on this side that are large enough to fit through. Meanwhile, Reginold, a faster runner than yourself, has disappeared around the north corner of the wall.
