Cadance and Twilight have discovered something about the Alicorn Amulet. Whenever someone rejects its promises of power, it weakens the Amulet's magic. In theory, if enough ponies should be tempted by it and reject it, it would destroy the amulet forever.
They summon the help of volunteers from across Equestria, in the hope of destroying it for good.

If you haven't been keeping up with cleverpun's collaborative project about various ponies trying to resist the Alicorn Amulet's lures... well, you should be. First off, I'm in it, and my chapter's just gone up. But also, there are a variety of authors, from the famous to the relatively new, who've offered up a wide variety of takes on the same core idea. Collectively, they make for a fascinating range of interpretations, and with the collab currently under 20,000 words, now's a good time to jump in and start reading before it gets too long (don't worry, all chapters are already written).
So go click that picture/title above and read it! And when you're done (or before, if you prefer), come back here and head past the break, where I'll talk about my just-published part in the collab: chapter four, the Carrot Top-centered Relevance. Find out more about what I wrote, below.
