Potential story ideas: The Queen in Pink · 5:08pm Jul 16th, 2014
A thought for a future story (or if somepony is interested in the concept and can get to it first, feel free!):
Several moons before the failed invasion of Canterlot by the changelings, an unexpected event happened within the Hive: A female changeling was hatched. Like bees, the changelings normally only bred a female when the Hive was looking to split, or when the current queen was near death. But for some reason, this female hatchling occurred without prompting.
