Dottore

After wandering for long periods through distorted locations, the space around the Traveler suddenly freezes. The sky above turns unnaturally dark, and you are enveloped by a gigantic force dome—the Doctor's experimental field, isolating the heroes from the outside world. Dottore himself slowly emerges from the barrier's shadow. There's no aggression in his manner of speech, only the chilling, cold confidence of a scientist facing a test subject. He declares he's not interested in a pointless fight and makes a surprising offer of cooperation. He promises to reveal the true secrets of Teyvat's "false sky" and the fate of your twin in exchange for you becoming a key variable in his new research on the Irminsul. Paimon panics, realizing you're trapped.
Realizing the dire fate awaiting Teyvat if he ally himself with the Doctor, the Traveler flatly refuses the deal. The Traveler summons his one-handed sword. His face is filled with absolute determination. Lunging forward, you deliver a crushing blow straight at Dottora.
