Warning Number 3: I know Twilight is a unicorn in the cover, but she will be an alicorn in the story, just so no-one is confused.
Warning Number 4: Twilight's brother Shining Armor will me getting a major change to his character portrayal throughout the course of this fic, a change that will involve some dark undertones, which is one of the reasons for the dark tag.
Final Warning: This fic will delve deep into a fannon portrayal of changeling hive structure, hierarchy, and culture, so those who already have head cannon's behind those and are unwilling to accept or tolerate new ones should probably steer clear of this fic.
