Dilan would have the least trouble traveling around Milarn right now. For the next few months, maybe even one or two years, there wouldn't be anyone strong enough to defeat Dilan and catch him. This was something Ariel Silvertale was pretty certain about after she witnessed his rapid growth.
"I don't think anyone believes that I need to brag about myself but I was only barely able to pass through the Gates and enter Milarn after paying the planet a humongous tribute. Most of my Power had been sealed at the beginning of the Fourth Awakening and it was not until two or three years ago that I regained my full power.
That being said, Dilan will probably only encounter the weakest form of True Gods, and even they won't be able to exhibit their true combat prowess for a while," Ariel had said at that time.
