Someone made a really long video on this theory months ago and it was a fairly good watch. They compiled all the little lore bits and hints to show she is out there biding her time and seems to be an even bigger threat than Hydaelyn was when she was at full power. And she split a world into 14 pieces and commited mass geno on all species of Etheirys. So they could do a lot of fun things with her.

Now the big questions are, will a writer they bring in have the chops to do it well? Will Yoshi PR be wise enough to allow a good writer to do it justice or will the character plot armor be so thick it hurts the story again? Will she be an actual threat or do we just need to invite her over for some tacos? Can they be more creative with her than reducing her defeat down to the power of friendship....again? Frankly there is so much potential, but at this point I don't really feel SE has the ability to do a story with so much potential, justice.
