How to complete In Desperate Times and ask the watcher for help in Diablo 4

Diablo 4 boasts one of the longest campaigns in the dungeon-crawler series, though plenty of side quests are scattered throughout Sanctuary. In Desperate Times is a side quest that you can pick up in the Imperial Library of Kehjistan.

Before you can jump into this quest to attain XP, gold, and renown, there is a perquisite that you will need to meet. You cannot actually start this side quest until you have fully completed the main campaign and then returned to Kehjistan.
