I've actually made many pictures of a "moon knight" Princess Luna wielding various moon blades, but for the sake of not spamming, I went with the one from Bloodborne. My friend on Discord thinks it's the best of all the moon swords in the From Software games. I've never played any of them, so I'll take his word for it. Enjoy!

Shoutout to drakizora for the excellent Nightmare Moon throne room background.
