Cephalon Fragments

Cephalon Fragments are scannable items placed randomly one per mission. Multiple must be scanned to complete a codex entry. Once the entry is complete, a picture along with a bit of text containing lore will unlock in the Codex. Once an entry is unlocked, you can move your mouse around the screen (PC) to change the volume of a noise faintly audible in the background. Pressing the jump button when it is loudest will cause Ordis to talk about his hidden memories, with a unique dialog for each entry.
