Fate's Atlas is essentially a visual guide to the story of Honkai: Star Rail, accessible in the bottom left of the Missions menu at all times. Every Trailblaze Mission is represented by a card on the timeline, and each card contains a short description of the key plot points at that point in the game.
What takes Fate's Atlas to the next level is that it's not only a display of Honkai: Star Rail's main story. Each Trailblaze Mission also displays relevant side-content like Companion Missions below the main card on the timeline. These sub-cards list the requirements you have to meet to unlock content, so literally anything you need to know is contained in the Atlas.
