Vector from the next My LotR Pony. As many people guessed/suspected/suggested, Princess Luna will be filling the role of Witch King of Angmar. Of course, she'll be donning the guise of Nightmare Moon for most of her scenes, but in the prologue, she's still Luna, only having just received her ring of power.
Which brings me to the next revelation: I'm going with rings. I was actually bouncing back and forth between cupcakes and horseshoes, but while cupcakes seemed awesome at first, they don't really work mechanically (very tough to wear a cupcake), and although horseshoes fit with ponies, they aren't especially interesting to draw (or at least I'm not capable of drawing them in a way that's aesthetically pleasing). So I figured, why not rings? Ponies may night have hands, but that doesn't stop them wearing gloves, right? They look a bit more like bracelets than rings, but I'll be calling them rings
One last thing I figure I should probably include here for clarity's sake: I'm going with the movie version of the intro. Hobbit history and genealogy is all very interesting, but it doesn't make for particularly interesting pictures (I'm sure someone will prove me wrong here eventually
That's all for now! I'm aiming to finish the next scene by the weekend.
*Vector subject to change in the final picture.
