Beware the bone-spiders.
The Catacombs are the domain of the Blind Man. It appears as an underground tunnel with passages where thousands of books are kept. These books are rumored to contain all the memories that the Blind Man has taken. The Catacombs are guarded by the Blind Man's bone-spiders, which weave the pages of his books. Sometimes, the Blind Man will let someone into the Catacombs for a short amount of time.
