With the mission finally completed, Klaus' bank account received the payment for completion a few hours later when he was in his apartment. Being such a high-level mission, the payment was just as tempting. He arranged to split it with Carion, but they did not see each other in person.
They both had to train as far as they were concerned.
The day they received training from Mr. Carter, Klaus realized how impressive his skills were.
Seeing Carion's training and how he had to train made him realize that he was very privileged because his attraction to positive or cursed energy was simply overwhelming compared to Carion's way of strengthening himself.
The positive energy coming into him depended on many factors, and willpower was so important that Mr. Carter had to nag Carion to get it right continually.
