Dubiously to Cinna
I think...while that may be true...this will not be the end of it.
Honestly, I had thought perhaps the Dark Knight was only a figment of the popular imagination, like the great bear Zubair in our stories of the Chosen Thoraya. Such a creature is unlikely to have ever existed, but it always scared me as a child, listening to stories of Thoraya battling a bear like a mountain...
But if the Dark Knight is real, then in all of the stories of the Chosen of the Light I read... And all our histories of the Calamity... The Dark Knight is truly the root of all evil.
