There Once was a Great Fairy

The fourteenth Hyrule Historia mission from Hyrule: Total War, titled "There Once was a Great Fairy."
As Prince Zant looks back to the time he first met Midna his forces prepare to siege the city of Elmenzhia, throne of the Great Fairy Una. Zant plans on capturing the Great Fairy to add her sorcery to his forces, but first he will have to fight armies of her own mages and swarms of her ravenous pet spiders.

I know it took years for her to show up , but at last Una is here.
