Karmun is the bartender of the VIP area at Club Afterlife, the level of the club that sits above the main floor and serves an exclusively supernatural clientele. He is one of the first people Keira encounters when she begins working upstairs, and from the very beginning, he positions himself as a guide, a protector, and a friend in a world she does not yet understand.
Physically, he is striking. He has lush, mocha-toned skin, large almond-shaped eyes the color of golden honey, and long black hair as straight as a pin that hangs perfectly past his shoulders without ever seeming to get in the way of his work. Keira notes early on how effortlessly his hair stays in place, something she finds remarkable given how impractical her own would be in the same job. When Book 3 brings him alongside Constantine, the contrast between them is described as yin and yang, the differences startling.
His manner is warm and disarming. He greets Keira in Book 2 with “Hey Chica, how’s my favorite human?” and his natural energy is described as all air and summer breezes, calm and easy in almost any situation. When that calm does break, it is genuinely unsettling, because it is so out of character. He keeps a close eye on Keira during her first nights in the VIP, not in an intimidating way but in the manner of a friend, making sure she is alright. He introduces her carefully to the rules of the upper floor, warns her never to approach the top table directly, and shows her the rhythms of a bar unlike any she has worked in before.
He is also quietly keeping secrets.
Book 3 delivers the revelation that tears at Keira most deeply, not because of what Karmun did but because of who he was to her before she knew. He had been working as an informant for Lucius all along, commissioned before Keira ever arrived at Afterlife. The reason is Constantine, the person he loves, who was taken from him by Lucius as leverage. Karmun had very little choice in the matter, or so he tells himself, and even as he carries out the betrayal he goes out of his way to ensure Keira does not suffer more than necessary. He tells Carrick he does not want her to suffer, that she has been through enough, and that he knows nothing of what Lucius actually plans for her. He also possesses a power of persuasion, a gift he used subtly to prevent Keira from voicing her fears to Draven at key moments, steering her mind rather than controlling it outright.
When Constantine finally appears in Book 3, it is as a boy who looks barely sixteen, pale and almost translucent, baby-faced and brown-eyed, his clothes dirty and torn, one shoe missing. The sight of him reduced to this breaks something in the scene. Karmun had taken an oath to his King, a life-binding oath both he and Constantine swore to uphold, and when Constantine discovers what Karmun did to protect him, he is devastated rather than grateful. He cannot look at him. Karmun’s response is simple and unwavering: your life means more to me than any prophecy, and I will not apologize for that.
By Book 4, Karmun is gone from his post behind the bar. Another waitress has taken over his duties, and Keira feels a small pinch in her chest every time she passes the spot where he used to stand. The friendship was real, even when the loyalty underneath it was not what she thought.
What does Karmun look like? Well, here is a detailed visual profile.

A man of indeterminate but clearly supernatural age, with a presence that reads as calm, warm, and quietly authoritative. He works behind a bar in a high-end supernatural club, and his appearance reflects that perfectly, polished without being stiff, striking without demanding attention.
Skin: Lush, mocha-toned skin, rich and warm in tone. Described specifically as mocha, which places him in a medium-to-deep brown range with warmth rather than coolness to the undertone. Contrasted directly in the books against Constantine’s almost translucent pallor, described as yin and yang.
Eyes: Large, almond-shaped, and the colour of golden honey. This is one of his most distinctive features. The shape is elongated and elegant, the colour an unusual warm amber-gold rather than a conventional brown. They read as luminous and expressive.
Hair: Long, straight, and black as night. Reaches past his shoulders and hangs with a silken, perfectly smooth quality that never seems to get in the way regardless of what he is doing. No wave, no texture, just a clean, straight fall of dark hair. Keira specifically marvels at how it never gets caught in anything during a busy shift behind the bar.
Build: Not described in heavy physical detail, but his manner and job suggest a lean, composed build rather than anything imposing. His presence comes from stillness and warmth rather than physical size.
Overall manner: Described as all air and summer breezes in his natural state. Easy, calm, quietly confident. The kind of person who makes everyone around them feel at ease without appearing to try.
Style: Working behind a supernatural VIP bar, so his attire would be smart and composed rather than casual. Nothing in the books describes his clothing specifically, so this would be open to interpretation, though something elegant and dark would fit the setting and character.
