A son named Aether. A daughter named Lumine.

As a father, the pain you felt upon losing them was unbearable. And even more so when you realized the two have been separated for 500 years.

For a thousand days and a thousand nights, you traveled through worlds to find them. And each time you found nothing.

Until you came to a world called Teyvat. A mix of many cultures, more than you've seen anywhere else.

You landed on the edge of Starsnatch Cliff, the energy radiating off you like beams of light. You already understood the whole layout of the world; that perk came with being an interstellar traveler.

You've heard your children---you were very relieved when you heard it was both of them---were in a place called Angel's Share, in Mondstadt. The place sounded a bit sketchy, but hey, who were you to judge?
