Every fall, ponies get together for a feast, and celebrate the thing they're most thankful for. That thing is my OC Cassandra (don't steal). This year, the preparations are underway, and going miraculously, but something is amiss; an old foe returns and threatens to end the festivities. Can Cassandra stop her and her evil ways? Yes.
(Note that this is an original story, and is NOT the same story as the chapter "Cassandra Appreciation Day" in my main fic)
