@ArthurBorg83156 This means that Vaatu could be reborn at the moment of Raava’s choice of a twin, where the particle remained in the niche and Vaatu grew from it. Or Korra herself objected to him from Rahab for a purpose that is still unclear
@ArthurBorg83156 I suspected that Unalaq, owning only water, would be reborn into the following magicians with one element. That is, Nisha could simply be an earth magician and such an unalaq would find the Turtle Lions and even the odds with his sister.
