Pacifer Clan was known of its insanely talented clan members. All of them were known for their undeniable prowess, but they were feared due to their power's unknown nature.
Every Pacifer had a mark on their forehead called Pacifer Seal. They were born with it, and it would only appear only after they became an adult at the age of 17.
Those who could materialize their Seal on a whim became a Hina Dmitra, and those who could utilize the secret Art of the Clan became a Maha Dmitra under the guidance of the previous Maha Dmitras.
The Seal was the source of the unknown power every Pacifer had, and it naturally became the thing that the Church wanted. Of course, none of them could ever get it, since the method of obtaining the Seal remained unknown up till now.
