At the beginning of his transmigration into a mortal body in Trion and escaping the Nexus for the first time as a mortal, Rowan was deeply aware that the most excellent tool of his enemies was deception.
They had to be deceptive, else their true form would be recognized by all, and they would not be able to hunt. Like wolves in sheep's clothing, they had to hide in order to feed.
Something horrible happened in the past that transformed existence into a realm of horror and damnation. The gods that lived above the mortals were no longer the source of enlightenment or hope; instead, they were the butchers.
Rowan had come to understand this after countless losses and sorrows, the death of his children, and the many joys he had lost along the way. He had to become a monster, think like a predator, become a butcher so he could make all that was wrong in this world to become right.
