Paul Grayson: The Cerberus Operative Who Turned

Paul Grayson was a Cerberus operative, certified starship pilot, and red sand addict who raised the autistic biotic girl Gillian as his adoptive daughter. Loyal to Cerberus and its human-supremacist ideals, he carried out many brutal missions for the Illusive Man before his love for his daughter turned him against the organization. Captured and transformed into a weapon by Reaper technology, he died resisting the control of the very enemy he had once dismissed.

The Cerberus operative#

In service to Cerberus, Grayson undertook many horrific missions, among them the sabotage of starships over colony worlds to release element zero in dust form. The worst of these, carried out over the colony of Yandoa, caused untold birth defects and produced thirty-seven biotic children, including the girl he would come to raise. Tall, thin, and dark-haired, his eyes reddened and his teeth made luminous by red sand, he could be described as xenophobic in keeping with his loyalty to a human-supremacist cause he genuinely believed in.

The Illusive Man gave Grayson the infant Gillian as a mission, ordering him to raise her as his own daughter and telling him she was meant to play a key part in humanity's future, even to become a savior whose potential Cerberus would nurture. Grayson was provided a cover story as an aerospace executive and a fabricated history of a wife lost in childbirth. In time he came to love the girl deeply despite the absence of any blood tie, and his pain at their separation when she entered a biotic research program deepened his dependence on red sand until the addiction became plain.

Turning against Cerberus#

As Gillian's father, Grayson was able to pass orders and special medicines to an undercover operative at the research project. When one of those medicines triggered a seizure and exposed the operative, Grayson was ordered to remove Gillian to a Cerberus facility, but was blocked by Kahlee Sanders. Unaware of his true allegiance, Kahlee traveled with him and Gillian to Omega, where Grayson secretly intended to meet an old partner who instead betrayed him.

Held prisoner and awaiting sale to the Collectors, the group was freed in a quarian rescue attempt, during which Grayson broke out, killed his betrayer, and recovered access codes to the quarian Migrant Fleet. Believing the quarians had taken Gillian and growing wary of Cerberus, he persuaded the Illusive Man to put him at the head of a retrieval team and led a squad of commandos aboard a fleet ship. There Kahlee Sanders caught him as he tried to flee with the stunned girl, and as she was beaten by the traitor Golo she pleaded with him to see that Cerberus cared only for his daughter's power as a weapon. Grayson made his choice, shot Golo dead, and warned Kahlee of the trap set to scuttle the ship.

Given into Kahlee's custody after the incursion, Grayson escaped rather than be delivered to an Alliance sentencing he was certain Cerberus would turn into a death warrant. He afterward sent word to the Illusive Man that he was leaving Cerberus forever, and secured Kahlee's safety by threatening to tell the Alliance everything he knew should any harm come to her.

Exile and recapture#

Three years on, Grayson had covered his tracks and conquered his addiction, building a new life on Omega under an assumed name in the one region the Illusive Man had never truly controlled. He kept contact with Kahlee Sanders without revealing his whereabouts, and despite his lingering prejudices took work as an enforcer for Aria T'Loak, even entering a relationship with her daughter Liselle. Tasked with raiding a rival gang's red sand shipment, he wrestled with the temptation to relapse and the resolve to remain the better man he had become.

His reprieve ended when the Cerberus assassin Kai Leng located him and reported his position. Kai Leng assaulted his apartment, overpowering Grayson and Liselle despite a desperate fight, and brought Grayson to a Cerberus research facility, but not before he managed to warn Kahlee and wipe his records.

The Reaper weapon#

At the facility Grayson was implanted with Reaper technology as part of an experiment to study Reaper enhancements, the Illusive Man himself present as the nanites took hold of his brain. Grayson fought the influence with every fiber of his will, and Cerberus was forced to wear him down with red sand. His body changed radically, his flesh stretched and half-translucent over the Reaper technology beneath, his strength and speed heightened far past human limits and his biotic power grown formidable, yet still he resisted.

When the facility came under attack, the now nearly enslaved Grayson was forced to seize an evacuation ship, and the Reapers drew on his feelings for Kahlee to send her a distress call. The hunt that followed led him to Grissom Academy, where the Reapers used him to raid the records of the biotic research program he had once been bound to. There he was confronted by David Anderson, and as his overtaxed body began to fail, the Reapers' control at last released him. He smiled up at Kahlee as she came to him, and Kai Leng put two rounds into his skull.

By the time of the war against the Reapers, records uncovered at the Cerberus headquarters of Cronos Station revealed that the implants forced upon Grayson had proven useful to Cerberus in adapting Reaper technology for its own forces, a grim final legacy of the man who had given everything to resist that same power.
