What if Annie was from Demacia?
And she and her parent were on the run from Demacian Government and they were chased into a forest that is on a one of the magical ley lines which give them the edge to fend off the Demacian. The Voodoo land could be like a safe haven for Witches and Warlock in Demacia.
An unforgiving barren wilderness, the Voodoo Lands were colonized by political and social outcasts from Noxus, known as the Gray Order, who sought to leave their neighbors in peace as they pursued dark arcane knowledge. The leaders of this outcast society are a married couple: Gregori Hastur, the Gray Warlock, and his wife Amoline, the Shadow Witch. Though survival was a challenge at times, the Gray Order's colony managed to thrive in a land where so many others would have failed.
This is taken from Annie's lore if you replace Noxus into Demacia and it would still make sense. They are political and social outcast because they know magic.
