Descendant of the Cancri Clan, who worshipped Athena back on Earth in the 20th century, Arpegius was born aboard the Cancri Clan Dredger in the Acubens system. Around 3308, Arpegius earned his provisional pilot's license and became CMDR Arpegius Cancri. He officially succeeded the clan dredger and attempted to start his own Kani Salvage Crew to operate it. However, his inexperience in business management led to the crew's failure to sustain the clan's upkeep.

Due to the continuous decline of the already struggling Cancri Clan, Arpegius was voted out by the clan elders, removing him from the lineage to prevent further tarnishing of the Cancri Clan's and Athena's names. Distraught, he left the clan dredger and ventured into deep space to gather his thoughts.

In the vast NGC 6188 Sector, he discovered a system isolated within a sea of stars and met an enigmatic man named Cloudspore Boyd, a former imperial who was tight-lipped about his past. Cloudspore spoke of a dream called Newfoundspace, a place where freedom reigned supreme, and anyone could join as long as they embraced the ideology of absolute freedom. Intrigued, Arpegius sought more information. Cloudspore shared stories of his ancestors on Earth, led by Peter Easton 1700 years ago, who liberated and ruled. Inspired, Arpegius decided to join Cloudspore in creating a new world of freedom and formed the Fogtown Saints squadron.

Together, they plotted a coup against the Cancri Clan to make the dredger an asset of the saints. With the assistance of the Consortium, introduced to him by Cloudspore, they stormed the clan dredger with thousands of ruthless criminals. They rounded up the clan elders and remaining members onto a large landing pad. Ignoring their protests and anger, Arpegius declared the dredger now belonged to the Consortium. He gave an ultimatum: join the Consortium or be ejected into space.

The head of the Eight Elders, pointed at Arpegius, calling him a scourge and a mistake that never showed have been born. Arpegius did not respond to this in anger. He calmly walked up the head elder, looked the man deep in the eyes as he continues to spout vulgarities against Arpegius' late parents, took out the sacrificial Athena blade and in one swift motion, slashed through the elder's neck.

Blood splattered across Arpegius' face, covering his glasses. The other elders fell silent. The head elder tried to grasp his neck but collapsed. Arpegius paused for a moment, holding up and examining the knife. He watched as blood dripped down the dagger, before swiping his finger across the blade to coat it in the elder's blood, and puts it in his mouth.

As he turned to the other elders, his face was no longer in a blank stare. His lips curled up into a grin, his eyes widened in excitement. Something ferocious has sprouted in Arpegius. Something he never considered. He looked at the remaining elders like an arachnid looking at his prey. He lunged at them with knife, releasing a brutal whirlwind of stabs and slashes. He was in such a fury he had forgotten time and the occasion, only thinking about killing those elders and when they stopped moving, he grabbed onto their limbs and bits into their flesh, ripping off chunks of meat with his teeth and swallowing their flesh before you after more and more bites. He ravages their corpse like a newborn spider eating his first feast.

When he came back to reality, his clothes was drenched in blood. The remaining Cancri Clan members, young and old, were cowering in fear. Even the Consortium mercenaries were staring in shock, cannot believe what just happened in front of their eyes. Only Cloudspore stood there unfazed, as he was the long-time ally of the Consortium trusted to overwatch Arpegius' first assignment. Arpegius stood up from the bloody mess on the ground and wiped the blood off his face with his sleeve.

He then walked back towards the consortium soldiers standing behind the guardrails of the landing pad, leaving the remaining Clan civilians unsure of what to do. When he got beside Cloudspore in the safe zone, he turned back at the Clan members on the landing pad and proclaimed.

"On second thought, I take back my offer. The Consortium has no use for wastes of air like you. You guys call yourself citizens of Athena, but what do you do for her? Nothing. You will definitely leech off the Consortium too. As a ally of the Consortium, I cannot do that..." he paused, deeply entranced in his delusions. "Yes, as the chosen member of the Clan, I am technically the current Cancri Saint. And as Athena's gold Saint of Death, I decree you all, to Death!" He cackled in insanity and activated the controls that send the landing pad up into the vacuum of space.

Cloudspore, impressed by Arpegius' ruthlessness and his dedication to the Consortium, decided that he could be more than just a crazed gang enforcer in some tiny corner away from the humanity, he could be made of much greater use for his boss. He revealed that while his official political pledge is to the emperor, his true allegiance was to the Pirate King, Archon Delaine. He welcomed Arpegius a spider of the Kumo Crew, which Arpegius gladly accept.
