It is a common perspective among most species that changelings are, for the most part, fairly weak creatures. They don't have the strength of a diamond dog. They don't have the speed of a vampire. Only a few have even a hope of challenging the knowledge of a dragon. Numbers, disguises, and their Queen is what most hives rely on. This is true of course, and Chrysalis knows it. Changelings are a fragile race, and if one day their unity would fail, a fail-safe must be ready. A fail-safe that, alone, could stand against any threat. Any situation. Any obstacle. A hero, which all could look to when times were dark.
That had been a long time ago.
