Khan didn't put everything in the back of his mind at that time. Paul and the others continued to manage the camp and take care of the injured, but he ignored them. He isolated himself in the previous gathering point and resumed training after changing his uniform.
Complicated thoughts ran through his mind during his meditation. Khan had grown so used to that exercise that he could lose himself in his reasonings while his flesh opposed the expanding mana.
The sharp pain that spread inside him from time to time didn't break his concentration and didn't interrupt the conflicting feelings that he experienced. He could think about his current situation, and everything appeared dark except for a few light shades.
That wasn't his first time experiencing that internal conflict, but he still couldn't grow used to it. The training camp on Nitis had been a heavenly place in his mind before the hunt since it helped appease Istrone's memories, but everything had vanished after Glenn's death.
