Tracking down and completing the White Nevron quests in Clair Obscur: Expedition 33 is a process that spans the entire game. You’ll encounter the first White Nevron shortly after reaching the Continent, and while most of the others are scattered around in areas you naturally have access to during Act 2, the last few are only accessible once Esquie learns how to fly again. The final reward for helping each White Nevron might be underwhelming, but you do get some excellent Pictos and even a costume while completing their individual quests. You can just attack them instead, but given what you’re missing out on, it’s not worth the trouble.
