Harbringer of Chaos, Coelus (1)

"I am not fearless, milord," Cyneah replied meekly. "Rather, I am full of fear that I want to give it my all."

She did not elaborate on what she meant, but every one near who heard her knew exactly what she did not say aloud.

'Neah...'

[This girl...]

After hearing Cyneah's words, Shaiha couldn't help but view her in a different light.

Honestly, the younger woman's very existence posed a significant obstacle in convincing Kyran to accept his identity as the Realm Scion. Thus, Shaiha would rather that she be removed from the picture as soon as possible. However, that would be impossible to do because she was not only someone very important to Kyran but also one of the successors of Ancient Magic Cores. 

As already assumed, becoming the Realm Scion meant Kyran had to gather all Ancient Magic Cores and absorb them. Obviously, this included the Soul core. But doing that would mean that Cyneah would never recover her sight.
