After he was done with placing a few seals on the mountain, Kretos headed down and declared the Northern mountain range as his property. If anyone would dare enter, he would hunt them down and kill them.
After hearing his declaration, of course, many demons would listen to him, but as always there were a few that didn't heed his warning. Since Kretos said what he said, it was obvious he was hiding a very precious treasure on the mountain, maybe it was something that could give a demon power to become as strong as a demon lord. The temptation was something most demons couldn't ignore.
Those brave yet foolish demons came to the mountain to find whatever Kretos was trying to hide. Yet the moment they set foot on the mountain their heads flew away from their body. The few who survived watched as the demons who came first became headless.
