It's time to introduce my character: Deir Licaon.
Deir Licaon was born in the death world of Zel Secundus (Calixis Sector). He entered the ecclesiarchy as a young novice where he devoted his soul to the emperor and to spread the words of the holy Emperor through the planet.
On a routine pilgrimage to the villages in the wastes the pilgrims encountered a rotten village with mutation and heresy. Zebulon, the Preacher of the planet confronted the mutants and Licaon watched how he was skin alive. Licaon escaped during the night, while the mutants were feasting with the corpse of the Preacher.
After that day, he seeks revenge over all sorts of mutant signs that he encounters, this has driven him to go deep into forbidden knowledge of heresy and mutants. As a means to spread the light of the Emperor Licaon has a duty to erase all signs from mutants and Heresy. Licaon embarked into a ship since some local authorities from the ministorium were investigating his access into the forbidden lore.
