The real one is obtained by defeating the Duke's Dear Freja in NG+ to get the Paledrake's Soul. Then trading it to a boss-weapon merchant for the Moonlight Greatsword. Alternatively, you can get the Paledrake's Soul by using a bonfire ascetic on the final bonfire in Brightstone Cove after defeating the Duke's Dear Freja in NG, as it will cause her to respawn as her NG+ version.
