The Tribunal was filled with powerful ones. The number of people suppressed by the Tribunal was staggering for the past millennium. Very few of those people were killed right away or executed hastily. Most people were imprisoned in the Black Dungeon to serve as research materials.
The divine smiths in the Tribunal had the greatest number of prisoners in the mainland to serve as guinea pigs. The punishers were some of their most matured works.
There were semi-metallic bones and transformable innards, blood vessels and muscles within the bodies of the huge beasts. There was also a mass of flesh and blood and pulsed at the core, which served as a power source to the punishers.
The messy pulp of flesh and blood served as a punisher's heart, which was also the control center of the beast. The punishers had no brains. Complex holy prose arrays littered within the heads of the beasts, which enabled to store multiple types of divine arts.
