"If I win, you will reveal to me not only the location of the portal and how to access it. But, you must also tell me everything there is to know about the world that you have come from. In addition, you must swear your life to me and follow me around for 100 days with your head lowered—begging my forgiveness." Ourami stated with a grin.
After thinking about it for a moment, Ourami felt that he would be letting Izroth off too easily if he simply got rid of him once everything was said and done. Instead, he could use the opportunity to soothe some of his anger and repay a portion of the humiliation he suffered.
Besides, with such a set of conditions, it would not be too late to claim his life whenever he pleased.
However, more than that, Ourami was curious as to the power structure of the other world. Was it similar to their own where pillars ruled the land? Or, was it a place of chaos? Whatever the case, even he knew that he could not take a careless approach.
