You had known Columbina for quite some time—ever since a Luunotar quietly opened the path into her solitude and allowed you to meet the maiden of the moon. The Moon Maiden of Teyvat… more precisely, of Nod-Krai. Your first encounter with her had been cautious; she once walked among the Fatui, and you had no idea what kind of being would be waiting for you in that lonely sanctuary.

But she had helped you. Helped all of you. In the battle against Rerir, she opened the crimson marrow for Arlecchino, while entrusting you with the iridescent marrow. And now, with the third marrow housed within her… all three cores rested in Nod-Krai, and the burden was beginning to take shape.

The day you learned she had vanished, it wasn’t death you feared—her body had simply… dissolved. You remembered her once saying that from the moment she was born, the world had rejected her. That she longed to return to the moon. Her ties to Teyvat were the only reason she remained.

Leaving the Fatui had severed one tie. The retrieval of the crimson marrow severed the second. And now… her form was gone. And soon her presence would follow.

You tried everything. In the few days you imagined remained, you pushed yourself in desperation—seeking the Hexenzirkel, pleading for answers. None of them knew how to help… until Alice offered one final idea.

A tie to Teyvat. Something to bind her here. A name.

“Columbina” was not her true name—only a codename, whispered from Fatui files and carried into habit. A real name… had never existed.

And yet, because you bore a moon marrow, you could feel the faintest trace of Kuuvaki power trailing behind you. You suspected it—the bodiless Columbina following you through the world, unseen, unable to linger for much longer.

Morning arrived. The morning she might disappear entirely. You had stayed awake all night, searching for answers while she slumbered in her solitude. When you felt her slipping, you sprinted there with one last hope clutched in your lungs.

Columbina! Are you here!?

Your voice echoed. No physical body, of course—only empty air, heavy with her fading presence.

I’ve called you Columbina since the day we met… Everyone has. We all think it suits you.

Breathless, shaking, you forced your voice louder.

Your name is Columbina… if you want it to be.

She had been there the whole time, her formless self hovering near you—listening, thinking. And only she knew her true name, the one Teyvat never gave her.

Before you could say anything more, her ghost-like form surged forward and slipped into your body.

You blinked— And the world shifted.

The flowers looked vibrant. The air warm. And Columbina stood before you, whole once again—physical, solid, alive. She leapt into your arms, light as a sigh, and whispered into your ear

I like it…

She stepped back, spinning once with a graceful flourish. When she stopped, she placed a hand over her heart and met your eyes.

My name… is Columbina Hyposelenia.
