Matthew McMahon

Reflective eyeglasses usually mask Matthew's narrow, black-eyed stare, giving little away beneath his arched brows. Now 66, he keeps his gray hair short and parted at the center, and his light-skinned frame, though elderly, is tall with an unremarkable build that lets him pass for any aging bureaucrat.

His work wardrobe rarely varies: a dark gray suit worn over a white shirt, finished with a deep teal tie. A silver band circles the ring finger of his left hand. Flashbacks to his younger days show the same parted style in dark hair rather than gray.

Blunt speech and an unshakable calm define Matthew. Life-or-death combat barely registers on him; assassination is simply the job, handled with the same professional detachment Yor shows, though her habit of leaving gore-soaked scenes draws his mild exasperation since the cleanup falls to him. He also prizes historical accuracy and personal responsibility, once rebuking Millie Myers for pinning the Second East-West War on Donovan Desmond without knowing the facts.

Service to Ostania anchors his identity. He intends to keep working for Garden as long as it needs him, war or peace, and demands matching discipline from partners, warning Yor to shelve personal feelings mid-mission. Yet he knows outsiders would call the work dirty, and beneath the severity sits real empathy: he grants Yor a day with her family after the Princess Lorelei assignment, and he counsels her on marriage using his own as the example, arguing that half-hearted commitment only wounds everyone involved.

Having lived through both wars between East and West, he expects conflict to persist as long as human nature does. He reserves genuine contempt for profiteers who treat war as a revenue stream, and though violence is his trade, he regards it as grim necessity rather than anything to celebrate. His deepest worry is domestic: he suspects Maureen would leave if she discovered what he does, yet against his own logic he hopes she would stay, and he credits that hope with keeping the marriage alive.

Age has not dulled Matthew's edge as an active Garden operative. One-handed, he throws the corpses of grown adults off a cruise ship, snaps an attacker's arms and legs, and pins the Knockman's hands with thrown darts. His durability matches: a hilt strike from the Swordsman slams him into a wall and briefly knocks him out, yet he recovers in time to shoot the Assassin Leader before Yor can be gunned down.

His reflexes leave smoke trails, literally. He slips knife swings, blocks blades with a broom, deflects one of Hemlock's thrown knives mid-flight with a well-aimed rock, and once vanishes from a vantage point to reappear at Yor's back before she notices. Firearms are his specialty, above all a sniper rifle that drops three targets before any can react, backed by a silenced pistol up close and darts or knives when the situation calls for them. He is also a fastidious cleaner, keeping the Princess Lorelei's deck spotless with broom and bucket even in the middle of a running battle.
