It's pure, and corruption hates nothing more than purity. "Nothing is sacred" is thier cry to justify their plight, as they challenge and corrupt more and more. Cadence and Shining represent marriage, love, as it should be, caring for one another before themselves, caring for each other as one would for themselves. My best friend just got married to a wonderful girl and everytime I see Army and Cadance I think of those two. There's something special about true love and we need to fight for it to keep it alive and pure.
