Close to his sister ...

Xylon's gaze bore into Karl, his mind flooded with memories of their tumultuous past. He couldn't help but feel a seething resentment towards this man who had once held such a significant place in Eva's life. 

The bitterness welled up within him, fueled by the lingering wounds of jealousy and insecurity that he couldn't recognize.

He recalled the countless times Karl had been by Eva's side, their laughter resonating through the halls of their shared home. 

They studied together, shared secrets, and formed an unbreakable bond that Xylon could never break. No matter how hard he tried, Karl remained a constant presence in Eva's life, a thorn in Xylon's side.

As the memories replayed in his mind, Xylon's grip on his dark energy tightened. The tendrils of power swirled around him, mirroring the storm of emotions raging within. 

It was as if the very essence of his being resonated with the intensity of his animosity towards Karl.
