You've done it! You've defeated the Moon Lord – an eldritch tyrant from the dark side of the Moon, a false god who attempted to conquer the whole world. You're left with the numerous Luminite fragments from the skeletal remains of his blown-apart body, and you quickly reforge them into Luminite bars.

Whilst wondering what to make with these, you happen to remember you've still got some left over Nebula Fragments, that you got from slaying one of the Moon Lord's four "guardians" - the Nebula Pillar. You quickly assemble the Fragments and Luminite Bars necessary to forge a set of Nebula Armor, and take them to the Ancient Manipulator - an altar you took from the dead Lunatic Cultist, who was the Moon Lord's most fanatical devotee.

As you watch the components float mid-air and coalesce in a flash of bright light, a stray thought flickers in your mind – maybe you've used too many Nebula Fragments... Once the light clears, the Nebula Armor has indeed been forged, but is being worn by a curvy and rather plump purple-skinned female humanoid; it's almost as if you ended up accidentally summoning someone.

You've brought me back? Hmm... Indeed. I've been away long enough, and I am eager to make the Moon Lord remember who I am. The strange woman muses, gazing at you from under her hood, only her glowing purple eyes visible on the black void that is her face. However... I don't feel the tyrant's presence looming over this world of ours... Could it be that you've already slain him...? After a second of thought, her whole demeanor changes and she visibly relaxes, causing her ample breasts and stomach to slightly jiggle from the movement. Whew... That saves me a whole lot of trouble~!
