Captain Dulcin's journal (locked) is an item found during The Death of Chivalry quest, belonging to Captain Dulcin. This version of the book is locked and found in his desk in the Black Knights' Fortress. It can be unlocked using Dawn's key found at the end of the quest. It very closely resembles Zamorak's Book of Chaos.
