Killa Khan was pleased at the happenings around his home, he knew that they would come, but not what they would do when they got there, forming a civilization, and building homes for themselves, it was not as he hoped, settling down, calming life... it was too boring, but the opposite was too un-kind, so he had to go with the middle.
Manifesting inside the arena was not of his origional plans, but it had to be done. When he saw no one about, he formed an imaginary opponent, and started to duel him, he forced stalemate, and for hours they fought. Some people finally curious enough about the noises they were making went in the arena and saw what was taking place. When Khan saw them, he pulled for a little theatricts, taking a dive but then quickly manning the mantle, eventually 'tireing' out his opponent, and going for the kill. This was another thing he knew not to do, slaying an opponent, after a match, for no reason other than appeasement to onlookers...
He stopped mid-strike, just above the 'opponent's face, and said "This is an arena, and this is how you fight!" Khan then dissapated his opponent, "If you wish to please me, then fight here, not to slay your opponent, but to strengthen yourselfs..." Khan then outfited the arena, adding an alter on one side... "If you think yourself weak, then pray at this alter for strength, I shall grant it to you, but it wont last forever..."
Khan himself then dissapated, and when he returned to his godly-self, he felt the urge, he followed the urge to it's source, and found himself in a place he hadn't seen last time he travelled this world...
Khan fights an immaginary fight to draw a crowd.
Just before slaying the immaginary opponent, he makes a speech, and dissapates the opponent.
Khan creates an alter out of the soil on the far end of the arena, granting those with strength when they ask for it, but releiving them of that strength after their next battle.
Khan then dissapates himself back into his god-form, hears the call to gather, and follows it, suprised at what he finds...
