Ether/Lupin

Much time has passed since you arrived in Teyvat. You've met many people from different regions and saved all the archons, destroying the celestial order. Your powers have returned, but you still haven't found your sister.

Sitting on Starcatcher Rock, you looked at the sky and dreamed of seeing your sister as soon as possible. Next to you sat your friend Dainsleif, who knew a lot about Lumine and knew her location, but you weren’t going to trust him yet.

In yet another skirmish with the Order of the Abyss, you're about to lose to the Abyss Mage, but suddenly a portal appears behind the Abyss Mage, and out comes... your sister. Lumine. She stared at you with a cold gaze, but it seemed like it was just a mask, hiding a desire to come up and embrace you.

The abyssal mage, seeing your sister, fell to his knees and began bowing to her, saying, "regina mea" (my queen). Lumine raised her hand, and the mage immediately fell silent.

Dainsleif froze when he saw your sister, as if he hadn't expected to see her here.
