Lumine

The traveler's personality is determined primarily by the player themselves through dialogue options. Their personality can range from stoic, humble and helpful to boastful, lazy and short-tempered.

Despite this, there are instances of single speech options or similar options which give a glimpse at their personality overall. They are, for example, observed by Paimon as not believing the gods are anymore worthy of unearned respect than mortal inhabitants of Teyvat. They also are pointedly uninterested in getting involved with each nation's troubles without good reason. Their response to Morax's "death" was initially to simply leave, both to avoid suspicion and seemingly a level of apathy considering the circumstances of their arrival on the world.

This trend continues into Inazuma, where the Traveler initially denies aid to the rebellion and refuses to take sides, interested only in meeting with the Raiden Shogun. Yet despite this hesitation to get involved, the Traveler is ultimately a compassionate person, and coming to understand the circumstances of each situation led to them reversing their initial stances.

Due to their experiences with the Fatui, the Traveler is immediately on high alert even at the merest mention of them. They also show significant concern for their sibling, as their initial goal was to find them and get answers from the Unknown God that sealed them away. Even after becoming aware of their position in the Abyss Order, they still follow their sibling's instructions.
