The Magic Association and Baato Nine Hells both belong to the 'order' camp in the Multiverse. The predecessor of the Association, the Magic Empire, even had a brief honeymoon period with the Nine Hells. However, during that time, they didn't see eye to eye and had ceaseless disputes and competitions with each other.
Because of this, the transmission gates of each level of the Baato Nine Hells have limited use for mage groups. Therefore, Kris and his teacher had to put in quite some effort to reach the City of Dis.
Firstly, they arrived at the lowest point of the lower plane realm, the plane which is continuously disintegrating - Grey Wastes. From there, they took a ferry controlled by a Yugros demon and spent an unspecified period traversing Underworld River, finally arriving at this infamous City of Devils.
