Recruitment Info[edit]


There’s not much I can pull about Kali’s plans through the channels you gave me, but I thought you’d want to know about a big player who’s already on the field. Nighthaven’s technology has always been its edge, and they have one person to thank for that.

Anja “Osa” Janković, trained in electromechanics, military engineering and robotics genius. Recruited into Nighthaven right out of university, founded their R&D department called “Quantum Concepts & Robotics”, trained in field operations by Kali herself. Boss lady doesn’t mention her much, so I got Ace to talk.

According to him, Kali and Osa tell each other everything. Kali is very protective of her, and not just because she’s her “golden goose”. Best friends, business partners, however you want to describe it. There’s a lot there that Harry could get at.

I looked at the tech that our Nighthaven specialists use, and they all share a signature – even after modifications, I can tell these are Osa’s prototypes. She probably made that gear Kali pulled out at the Invitational, the outfit you told me about.

Now that she’s a team captain, I’m not surprised that Kali would bring in one of her own people. I’m surprised Osa is the one, though. She has the skills and the experience, but I thought someone like Kali would keep an asset like her away from the line of fire.

Speaking of which, the device she’s bringing is sure to play on lines of fire. A clear shield with mechanical claws that digs itself into surfaces and frames? Its defensive capabilities designed for offensive missions might make Mira jealous that she didn’t think of that first. Still, I’m not seeing anything yet that suggests Nighthaven is trouble.

Maybe you misjudged, Ash. Maybe Kali is just more human than you expected. Maybe she just doesn’t play by the rules, and you don’t know what to do with that. Check with Harry after his assessment. I’ll keep digging.


“The best ideas come to me when I exclude rules and guidelines from the equation.”

Born to the Janković family, owners of European toy stores, Anja traveled with her parents constantly, so she never felt stable until she moved in with her aunt in Croatia at the age of 6. She began her schooling there and learned the family trade of toymaking, all the while developing a near obsession for 60s science-fiction films.

She followed her passion for creation and technology and studied electromechanics at a vocational school, and then military engineering at the University of Zagreb where she excelled at robotics engineering. She found herself isolated due to her unorthodox approach and others’ attitudes towards her transition, so she focused on her work. Her unique perspective and raw creative ability set her apart from her peers and got her the attention of Kali, who was in the country looking for recruits. An offer followed, and Janković joined Nighthaven.

The company’s success can be largely credited to Osa’s inventions and her field work. Her efficiency and the versatility of her arsenal have given them an edge in every recorded operation, and by proving herself to be a dedicated and reliable asset she earned the choice position of Nighthaven’s head of R&D.

Psychological Report[edit]

Specialist Anja “Osa” Janković didn’t shy away from letting me know that speaking to me about personal matters was a professional courtesy; she always has work to get back to, and time with me is more of a distraction than anything else. […]

In all matters, she is grounded by the meticulous precision that her aunt taught her yet driven by a sense of wonder. She attributes this to her favorite childhood movie, Empress of the Plutomatons (1967). As I understand, it was filled with futuristic technology and colorful imagery, and was ahead of its time in the presentation of a strong female protagonist. It’s easy to see the trajectory between that little girl, wonderstruck by robots and spaceships, and the genius that she is today.

Her creations are more than their function, to her at least. She walked me through the process of developing Wamai’s Mag-NET Systems, from idea to working prototype. Before she even thinks about materials and calculates the physics of a device, she draws it out with a specific aesthetic and color palette in mind. Aruni’s prosthetics, Kali’s Masterframe outfit, Ace’s Breachers… they’re more than just equipment, they’re art pieces. […]

She credits her success in equal parts to her natural talent and the affection of her loved ones. In both her career and her transition, she could always count on the support of her older brother, her aunt, and Kali. She writes to her family from every corner of the world where her work sends her and she describes her bond with Kali, her “boss”, as an unbreakable sisterhood built on mutual respect.

With Nighthaven, she found agency and merit, as well as a circle of friends with whom she could be herself. Despite her disregard for my work, I expressed hope that she would eventually come to trust me as she does them. I also asked if I could borrow a copy of Empress of the Plutomatons; it sounds like a lot of fun. And who knows? I might learn a thing or two.

Most shields are bulky and singular in function, but the Talon-8’s adaptability makes it incredibly efficient in establishing forward positions…”
Dr. Elena “Mira” Álvarez, Director of R&D (Rainbow Six Siege's official patch-notes)
Device: Talon-8 Clear Shield

Operator: Specialist Anja Katarina "Osa" Janković Evaluation Lead: Specialist Monika "IQ" Weiss

I'm not sure why Mira wanted a second opinion on the Talon-8; Osa's work is stellar, and her designs have been a staple in the Program ever since Nighthaven's arrival. Still, I was excited to get my hands on another great piece of equipment.

(Comment_E. Álvarez: Just making sure I didn't miss anything. Kali made it sound like Janković is above evaluation. -Mira)

Knowing the versatility of Osa's gadgets, I'm not suprised by this one's performance level. I can't overstate the importance of being able to set up defensive positions anywhere. This shield's ability to adept to any space without blocking lines of sight will be an asset in all operations.

The composition makes it lighter and quicker to deploy, while the mechanical claws ensure it stays wherever you place it - even on a window ledge. The clear bulletproof glass is the icing on the cake - kind of makes me wish I had one of these.

(Comment_E. Álvarez: Design is both impressive and appealing. No modifications needed. -Mira)
