After the battle with Evior, Kretos became rather famous in the school. Many students wanted to learn from him, and lower level teachers also wanted the same. This greatly annoyed Kretos, so he gave the task of teaching them to Afeus. If Afeus is able to teach the basics of mana control to the students, Kretos was willing to acknowledge him as his disciple and would teach him greater mana control.
This motivated Afeus greatly as he guided the others in basic mana control. While everyone was going crazy regarding the discovery of spells that didn't need elementals, Kretos decided to rest.
As he closed his eyes shut, Kretos immediately went to sleep. He would usually be only half asleep since enemies could attack him at any time and he needed to be ready, but this time he was in a deep sleep. As he was sleeping he had a dream, a very lucid dream.
