3/14/24 Still Alive Edition

There's only one pony in Ponyville that the Mane Six have never met. Pinkie Pie has never thrown him a party, Applejack has never sold him a mug of cider, and Twilight has never seen him check out any books. And as far as that unicorn, Lapis Print, is concerned, that's exactly how it should be.

Lapis can't risk them knowing where he lives, what he does for a living, or even what his name is - if he gets his way, the Mane Six won't even know he exists, and nopony in Ponyville will miss him once he's gone.

It should be a piece of cake - after all, it's not like the biggest magical power in Equestria is about making sure everypony looks out for each other, right?

(Rated Teen for language - mental cursing mostly.)

The Elements are sent as backup to help solve the mystery of the changeling's purpose in the wasteland that was Flutter Valley.
With Cadence, Shining Armor and a contingent of guardsponies will they be able to sort things out peacefully or will Cadence's resentment of Chrysalis lead to war against thousands of changeling drones?
What of the fabled and long dead sunstone, said to have the ability to radiate warmth and love if only it wasn't cursed right along with the valley itself?

Admittedly it's a bit of a G1 crossover, and my first pony fic besides. Try not to hold that against it. I feel the mythology of the sunstone was inadequately explored and I rather felt that the changelings might make good use of such an item.

This will be four chapters, about 10,000 words each and will NOT be abandoned before completion, Pinkie promise.
