That was REALLY good and im glad that She didnt kill his parents, Sadly Elkin still thinks that the sun knight did.
now here's a theory with the name of the story being the basis of this, Karia sun has set meaning she has given up on life and just doesn't care anymore thus her powers have also dwindled (i would imagine that her magic blast would be weaker too but she hasn't casted it thus she hasn't seen it) this sickness she has is just old wounds coming back due to her powers not holding them back anymore.....just a thought.
