NPCs breathe life into the game worlds players inhabit. Cannon-fodder, quest-givers, or trusty shopkeepers, NPCs exist for immersion and entertainment. Legions of players would admit that these non-playable characters are used and abused on a regular basis.

What’s rare is for an NPC to disrupt this established status quo. The paradigm shift rests on many factors. It could be an NPC’s seeming omniscience of a game world and its events. It could be their mysterious or unexplained origin, lending these characters a strange, alien quality. They may also exist as devices, potential outlets for meta-commentary by game developers.

In their debated causes and effects, these mysterious and enigmatic NPCs stay with playerslong after the game ends. Here are the most mystifying of all.

M’aiq the liar - encounter

7M’aiq The Liar - The Elder Scrolls

M’aiq. Or rather his father’s, father’s, father (according to him) has wandered Tamriel since the events ofMorrowind. His long lineage only adds to his mystery and otherworldly nature.

The Dragonborn can encounter M’aiq on the roads ofSkyrim. It’s unclear whether he’s the font of all knowledge or just a charlatan as his name suggests. What is clear is that he knowssomething.He purports there’s a distinction between Alduin and Akatosh, as well as giving clues as to why the Falmer are blind. How does M’aiq know these things? Perhaps players will never know.

Ulysses Fallout NV 2010

6Ulysses - Fallout: New Vegas

From the outset ofFallout: New Vegas,the player has to contend with the sense that important information is being withheld. The Courier is blown around by forces much larger than themselves. Ulysses is the personification of this mystery. His existence is drip-fed through encounters in the main quest, as well as the DLC. This figure has orchestrated significant events in The Courier’s journey.

He clearly has a personal stake in the protagonist. As another courier, he nearly takes the job to deliver the platinum chip but refused when he realized the player character was up for the same job. He sought out Father Elijah and the scientists at the Big MT, again mirroring The Courier’s actions. Eventually, he invites The Courier to find him in thedesolation of The Divide. All is revealed in this ravaged place as The Courier walks this road, alone.

Blind Man Cassidy Camp

Blind Man Cassidy. This prophetic and mystical figure had the insight of a shaman. For the reasonable price of a dollar, he would regale Arthur with clues to his fate.

He notes how Arthur’s “Father” has been coerced by the one with the “forked tongue.” There’s no doubt that he’s referring to Micah’s manipulation of Dutch. Heeven predicts Arthur’s death: “The man with no nose is coming for you.” The grim specter of death approaches. His biblical undertones and attuned insight give him a foreboding presence. He reacts to the player’s honor level and their decisions, so he serves as a device for Rockstar to comment on player action.

Elizabeth, the girl Booker’s seeking, is actually his daughter. Also, the Lutece twins are parallel versions of the same person, Rosalind Lutece. Rosalind created the technology that makes all this time-hopping possible. The encounters with the twins convey that the events of the game have been carried out an innumerable number of times, with innumerable outcomes.

3G-Man - Half-Life Series

Seriously, what’s in that briefcase? G-Man. Government man? God man? Not who is he, morewhatis he? His strange intonations, unchanging appearance, and time-stopping abilities all hint he’s definitely more than man.

He appears in mind-bending, dreamlike sequences, often praising or mocking Gordon and Alyx. He then references his seemingly metaphysical “employers,“before offering a choice. He has orchestrated events since the resonance cascade, setting the wheels in motion for The Combine invasion of Earth. His nature, allegiances, and wants are still a mystery to this day.

2Mendicant Bias - Halo Trilogy

Mendicant Bias is more integral to shaping theHalouniverse than The Chief himself. Players will be forgiven for not being aware of the AI’s existence, or its hand in the orchestrating of cataclysmic events. The intelligence plays a large role in the more esoteric part ofHalo’slore, but discerning players can encounter them in the original trilogy.

God? The Devil? Death himself? An innumerable number of theories have been devised to try and ascertain the identity of this NPC. There’s no doubt that the entity is metaphysical, other than that, its origins and motivations can only be speculated. He refers to himself as “an accountant,” seemingly weighing up the morality of others.
