  "backwards, it may also move a frontal part backwards. To kill a Dragon, "
  "you need to hit each of its segments. "
  "The head will regenerate on the "
  "turns the Dragon is not moving, so you will usually have to hit it with "
  "your last attack; otherwise, if the head is healthy, it may breathe "

  "factors, and thus "
  "2097152 varieties. You'll have to find a "
