As much as Edith wanted to follow in Lirian's footsteps she knew that she couldn't, and if Lirian returned from his trial successfully the gap between them would only grow, she looked at Lirian with unwillingness in her eyes, but she was afraid that she wouldn't be able to change his mind.
The Emperor looked at Lirian with a hopeful gaze, he'd be lying if he said he wasn't slightly happy to hear what Lirian said.
He knew Lirian's talents better than anyone else, so he didn't doubt Lirian's ability to complete the trial through a harder method, what excited him though was the idea of Taliyah returning.
It had been 14 years since Taliyah left to raise Lirian on Xelia and in all that time they weren't able to meet even once, the emperor had his own duties and experiments that occupied his time and whenever both he and Taliyah had an opening in their schedules they would call each other.
