My Knight. Killua x Gon. Prince and knight AU.

Hidden Power

     Illumi and Hisoka stood at the edge of a cliff overlooking the peaceful forest land of Gludal. 

     "Do you feel any sense of ownership over what you see right now?" Hisoka asked. 

     Illumi turned his head so his dead pan eyes matched Hisoka's. "This is not my kingdom to rule over. It's Killua's. I'm just his older brother." Illumi explained. 

     "Hmm, and why is that? You seem to be more skilled than Killua, well at least when it comes to the more important things." Hisoka pointed out. His eyes ran over Illumi's body as if drinking in all his power. His licked his lips slightly. 

     "Please stop ogling me." Illumi ordered. 

     Hisoka just stared back at him with his peering, golden eyes. 

     "Killua was born with not only the best source of nen out of the five of us, but he has the best controllers in every part of his body. He is the perfect nen user and could potentially be stronger than even our grandfather when it comes to nen." Illumi explained. 

     "Why haven't you taught the young prince any nen then?" Hisoka asked. 

     "He's too young. We trained him to a certain degree but his nen needs time to truly mature." Illumi explained. 

     "That's not true at all you know. Any knight can use nen at any age and it works fine. It's all about genetics and the person's personal strength." Hisoka replied. 

     "I am aware of that. I'm not an idiot." Illumi snapped back. "But it is our tradition to make the strongest nen user out of the royal family heir, and to teach them the art of nen at the age of 14." Illumi explained. He turned to start scaling down the mountain. 

     "You have a lot of control of your nen throughout your body. I'm sure it's ease for you to do inner spells." Hisoka mentioned. 

     "That is true, but my amount of nen is fare less than Killua's." Illumi replied. 

     "That young knight that was sent to watch after the young prince..." Hisoka brought up. 

     "You mean one of the three traitors. I'm aware." Illumi added. 

     "He was quite strong was he not. I could just see the nen festering in his strong little body. Ugh, it took everything in me to not just feel that energy for myself. In whichever way I can get." Hisoka told Illumi his voice getting softer as he drew more pleasure from the thought. 

     "I'll never understand you, you creep." Illumi commented. 

     They made it to the bottom of the cliff and Illumi brushed himself off. 

     "And do you really want to?" Hisoka asked as he swept off some dirt off Illumi's shoulder. He stared intently into the princess jet black eyes. He took a lock of his hair and brushed it toying with it a little. "You know I'll entertain myself with whatever interests me." Hisoka hissed.
