Stronghold notes

The Stronghold notes or Stronghold of Security - Notes, give some information about the floors in the Stronghold of Security. It is a green book with an 'S' on it.

It is found just inside the Stronghold of Security in the Barbarian Village west of Varrock by searching a dead explorer, or on the shelves in a house.

This dead explorer is Litara's brother, who tells players to look for him. He is a skeleton and can be found immediately from the entrance to the stronghold.
