You’ll encounter a number of challenging puzzles in your TFS playthrough, and the Exegesis puzzle is one of them. To complete it, you’ll first need to know how to craft light motifs in Destiny 2: The Final Shape.
How to Get a MOTE OF LIGHT in Destiny 2 The Final Form
There are two types of motes that you need to find in Destiny 2 The Final Shape: light and dark. Dark motes are easier, as you only need to defeat the Eater of Light and Darkness. You will find many of these Hive Knights around the area where you need to complete the puzzle.
Finding Light Motes in the Final Shape expansion is the tricky part. You still have to kill the 'Eater of Light and Darkness', but you have to do so with the Relic Shield (Captain America style). To use the shield as a weapon, press R1 on your controller or C on your mouse and keyboard.
Once you have the motes, you need to place them in their corresponding fonts, light on light, dark on dark. The Exegesis puzzle has four fonts to match: two light and two dark.
