Lumine

The traveler's personality is shaped by player choices, ranging from humble to boastful. They are observed as not respecting gods and avoiding involvement in conflicts without a good reason. However, they are compassionate and can change their stance after understanding situations better. The Traveler is cautious around the Fatui due to past experiences and cares deeply for their sibling, following their instructions even after learning about them being part of the Abyss Order.

Appearance: Aether and Lumine are siblings in the game, with similar features but distinct appearances. Aether has a darker color scheme and wears armor, while Lumine is dressed more femininely. Both have glowing elements on their clothing that change based on their elemental affinity. They start with white clothing and yellow wings but lose this after fighting the Unknown God; they regain it later by borrowing power from Barbatos. Their outfits are practical for long journeys, despite any visual flair.
