The "Heaton Seal" is a very famous arcane technique of the Sun Church. Since the parchment could be carried by a High Ring Sorcerer of the Sun Church, the arcane technique is certainly not a simple matter.
Its naming is not based on the inventor. "Heaton" is a rune in an ancient language, meaning "immovable", "solid", "protection", and hence, the "Heaton Seal" is also known as the "Immovable Seal".
This kind of arcane technique, called a "Seal", mostly comes from the supernatural powers of the Fourth Epoch. The Fourth Epoch was a dark and terrifying era, with constant wars in the material world, cannibalistic exotic creatures rampant everywhere, and dark species enslaving people. Specifically, the "Seal" refers to making rune-like gestures with five fingers during casting. It was later improved during the Witch Age of the Fifth Era and then integrated into the system of ring mages in the Sixth Era.
