Walkthrough Guide to all locations of the white Nevrons to complete Blanche NPC quest line in Clair Obscur Expedition 33 based on my playthrough. What's the rewards for completing Blanche quest line and for each Nevron and whether you should attack Nevrons or not. About Blanche Quest in Clair Obscur Expedition 33: The Blanche questline in Clair Obscur: Expedition 33 is a pivotal late-game side quest found in the hidden The Fountain area, reachable only after acquiring Esquie's flight ability post-Act 2. This optional quest acts as the culmination of interacting with all the friendly White Nevrons encountered during Act 1 and Act 2 side quests, including figures like Jar, Demineur, Benisseur in the Red Woods (requiring the 50k Chroma donation), Hexga, and others; your key choices throughout these Nevron quests regarding whether to kill or spare each Nevron determine the outcome with Blanche. If you successfully completed all Nevron quests and consistently chose to spare every friendly Nevron, speaking to Blanche in The Fountain will result in a generous reward of 100 Colour of Lumina and contribute to the Aiding the Enemy achievement; conversely, if you killed any friendly Nevrons, Blanche will engage you in a challenging Blanche boss fight instead of offering the large reward. 0:00 Intro 1:04 Jar - Spring Meadows - Act 1 3:40 Demineur - lying Waters - Act 1 5:39 Bourgeon - The Small Bourgeon - Act 1 7:59 Hexga - Stone Wave Cliffs - Act 1 10:58 Benisseur - Red Woods - Act 1 12:14 Troubadour - Stone Quarry - Act 2 13:35 Portier - Stone Esoteric Ruins - Act 2 16:27 Danseuse Teacher - Frozen Hearts - Act 2 18:56 Side Notes 20:32 Blanche - The Fountain - Act 3 (Reward) NOTE: There might be other Nevrons related to the quest and I don't know if there is a minimum to get the reward, this is how I did it myself to get the reward.
