Nothing annoyed a God more than lacking knowledge and not having a reasonable means of acquiring it. Sol hated the fact that he had to kill more supernatural beasts to gain more of these tattoos and more memories.
Where would he find supernatural beings in the capital?
Sol was not stupid enough to believe that the Discord wyrm entered the capital and of all the soldiers, adventures, and court mages they could call to handle this, it was a few students.
No one knew Martial Saint Kratus more than Sol. The man was cunning and cruel, so diabolic that Sol acknowledged this man was only second to him.
This man played a major role in his death because he was the only one who succeeded in separating Sol and Cyrus. He helped them kill Cyrus while Sol was left to deal with the human Emperor, the Elf Queen, the Hail Family patriarch, and his family of werewolves and so many more.
