Ronnie Anne did escaped due to a female villager who loved lions as a child, she was the one who freed Ronnie Anne and let her escape, but since the death of Lincoln took place, but the villagers and poachers thought it was over. But nope... the legacy of the white lions continued, Ronnie Anne had Lincoln's cubs. Half of her cubs were white, securing the bloodline of the white lions
And it's in a place where a huge valley was ruled by a family of lions that lived there for generations, but these lions were known as protectors of the valley they had called home, these lions were white lions that were Lincoln's ancestors and they were the last of their bloodline, so Lincoln's thought to be the last white lion
