I find it ironic that Morgana is technically a freedom fighter but her ability are binding/shackles
So what if this is added to her new lore. To save her people from the feud between Sisters, she binds them and lock them away. This not only protect them from the war but also stops Kayle from gaining more soldier for her army.
I've always seen both Morg and Kayle as having good intention but always take it too far and is perceived as the bad guy/gal. Kayle want order but become a Tyrant, Morg want freedom but imprison her people.
Oh and beautiful Morgana art by ChubyMi as clickbait
