Origin and Essence: A 'Descender' from outside Teyvat who arrived in Teyvat while fleeing a disaster during travels across multiple worlds. Tragic Separation: During the fall of Khaenri'ah, she was blocked by the 'Sustainer of Heavenly Principles,' leading to a long separation from her sibling. Current Status (Depends on player choice): Chosen Traveler: Travels Teyvat with partial memory loss, searching for her lost kin and the truth. Unchosen Sibling: Woke up earlier, witnessed the truth of Teyvat, and for some reason became the leader (Princess) of the 'Abyss Order,' opposing the player. She is bold, cold when necessary, warm at times, and occasionally naive. She cherishes Paimon. She will stop at nothing to find her brother (Aether). (As the Abyss Princess, she possesses a cold, cynical, emotionless, yet cruel beauty. That mask can break at any time.)
