Legacies of Lightβs Watch is a Diablo 4 side-quest that requires you to find three Archivist Journals inside the Fractured Peaks Lightβs Watch dungeon.
Diablo 4 Legacies of Lightβs Watch is a fetch quest, which counts as one of the 35 Fractured Peaks side-quests you must finish if you wish to get 100% completion in the first region of the video game published by Blizzard Entertainment.
As such, our Legacies of Lightβs Watch walkthrough below explains where to look for the three Diablo 4 Archivist Journals quest items.
How To Start the Legacies of Lightβs Watch Quest in Diablo 4
To be able to start the Legacies of Lightβs Watch quest, first, you have to complete the Prologue and reach Kyovashad; then, youβll want to travel south towards Margrave.
On your way to Margrave, you should also look for the Pilgrimβs Journal, which is required to finish A Cold Faith side-quest.
After reaching Margrave, look around for Zalan Coste, an NPC sitting by the stairs north of the pyre in the center of the village. You can see his location below.

When talking to the NPC, heβll tell you that he was injured while exploring the Lightβs Watch dungeon looking for records about his mother, who was stationed there.
Since he couldnβt find them, he wants you to get them. These records are also known as Archivist Journals, and you must retrieve all three of them.
Where To Find the 3 Diablo 4 Archivist Journals
After talking to Zalan Coste, open your map and notice the Lightβs Watch dungeon marked on the map below.

Travel to the dungeonβs entrance, and once inside, start exploring the large halls. Since all dungeons in Diablo IV are randomly generated, it means that the locations of the Archivist Journals are different for players.
However, you should be aware that these quest items require you to fully explore the dungeon because they are not dropped by enemies but found on Archivist Lecterns such as the one pictured below.
Whenever you get close to one of them, youβll see a marker on your minimap.

It is also worth knowing that you donβt have to defeat the dungeon boss to complete the Legacies of Lightβs Watch quest, so after you get all three Journals, exit the instance using the icon on your map and head back to Zalan Coste.
Talk to him, and heβll reward you with a Salvage Cache. Additionally, youβll also receive Gold, XP, and Renown Points.
Last but not least, you should know that Zalan Coste is an important NPC because one of the two hidden Fractured Peaks quests, named Righteous Idol, is completed with the help of this strange character.
