The captain of the Sunlight Scripture of the Slane Theocracy was named Nigun. His mission was to assassinate Gazef Stronoff, the strongest warrior in the Re-Estize Kingdom. Despite being deeply religious and believing in the power granted to him through his position, Nigun's arrogance led him to act recklessly. When he was defeated, he tried to throw away his subordinates to save himself. As captain of the Sunlight Scripture, Nigun had been involved in many illegal activities. Recently, he was tasked with eradicating a demi-human village but was stopped by Blue Rose. The leader of Blue Rose managed to scar Nigun's face as a reminder of his defeat.
After being taken prisoner by Ainz, Nigun and the Sunlight Scripture are being questioned, tortured, and experimented on by Neuronist Painkill under Demiurges supervision. Nigun was the first one to die, tortured to death while being questioned.
