Bercouli Herlentz

Bercouli (ベルクーリ), also known as Bercouli Synthesis One (ベルクーリ・シンセシス・ワン), is one of founders of Rulid Village, as well as the Knight Leader of the Integrity Knights and the oldest Integrity Knight in existence.

Mythology
According to the legend of «Bercouli and the Northern White Dragon», on a certain day during the peak of the summer, Bercouli noticed a lump of ice floating in the Ruhr river. In amazement, Bercouli walked upstream along the river to find the source of the ice. As he continued to follow the river, he soon arrived at the «Mountain Range at the Edge» and found a huge cave opening.

After entering the cave and overcoming various dangers, he arrived at the largest hall within the cave. There he found a white dragon, rumored to be the protector of Human World boundary. The dragon was sleeping on an incalculable amount of assorted treasure, among which was a beautiful long sword, called the Blue Rose Sword. Bercouli wanted to own the sword no matter what, therefore, he softly took the sword without waking the dragon up and tried to run away with the sword. However a blue rose suddenly grew out of the sword and tangled him, which made Bercouli fall and awaken the dragon with the noise.

Bercouli then put the sword back in its rightful place and was thus forgiven, or so the legend says.

History
Bercouli lived some time between when the Axiom Church was founded and Quinella had usurped the power from the Cardinal System. At the time, Bercouli was both an unparalleled swordsman, who had even won in the Empire Swordsmanship Tournament, and a hero who loathed the rule of the Axiom Church, thus he led his comrades to one of the remotest region of the Human World where they pioneered their own village, named Rulid, and Bercouli became the first guard chief of the village.

However, at some point after Quinella became the Administrator, Bercouli found his way to the «North Cave» where he attempted to cross into the Dark Territory. Sensing this, Quinella abducted Bercouli and used him as the first test subject in her experiments on manipulating Fluctlights. Most of Bercouli's memories were damaged during the experiments and he was later frozen to be preserved for future experiments. However, when Quinella failed in her attempt to take control of a nun’s body and accidentally allowed Cardinal to assume the young girl’s body and escape into the Great Library Room, Quinella decided to create absolutely loyal escorts to protect her. Bercouli was then unfrozen and subjected to the Synthesis Ritual, during which he became the first Integrity Knight.

Some time after Bercouli was turned into an Integrity Knight, he was sent back to the North Cave, where he was ordered to slaughter the white dragon guarding the northern border of the Human World. Though, for some reason, he did not take the Blue Rose Sword from the dragon. This is likely because the Blue Rose Sword requires a large Object Control Authority value to wield, which Bercouli did not have at the time.
