Not sure it's allowed but I had an idea for a crossover that seems to fit.

A different take on the Sliver Eye power.

~~~

It's the night that Becaon fell. Ruby is bested by Cinder only for to awaken in a garden. Inside of it are pictures of her mother starting form Beacon all the way to the last days of her life at home with Ruby, Yang and Tai

To her shock she finds a doll that looks eerily like her mother dressed in her white hood sitting under a tree with the message, "Go to the top of the hill."

She follows the trail through the garden up a short winding hill to a small temple to the two Gods. Countless weapons lie against the statues, even hers.

She takes it and finds a message etched into the stone, "Awake form this Dream... Make this night one to reamber. Kneel and pray for new life infornt of the God of Light to wake form this Dream. Kneel and pray to the God of Dark to strengthen yourself with the blood that drips form your weapon. Good hunting."

Love to see what someone else could come up with this idea. Less unimaginable horrors and more along the lines of blessings.
