Who was Sophie designed to fight against?
The Black Swan made it very clear on numerous occasions that Sophie was made to help their world see all the unfair prejudices, hence her human upbringing. That was their inutial goal.
And the Neverseen never looked like the Black Swan's №1 enemy. I mean, both groups have been present FOR A WHILE, but it's only, like, in Everblaze that we actually discover the Neverseen's name, so it's either the Neverseen are really good at hiding or the Black Swan never cared about them. The reason why the Black Swan is onto the Neverseen now is because the latter kidnapped Sophie and Dex, which was their first real move.
BUT if Sophie wasn't designed to fight the Neverseen, why give her all the abilities? She was meant to be a warrior, a fighter. But who did the Black Swan want her to fight against? The Council? Or have Forkle always considered them going to war with someone else?
