Karina Marković

Summary
Karina Marković initially is an antagonist (but later becomes a protagonist) of the novel that features the Metaverse.

A woman of Yugoslav (specifically, Serbian) descent, Karina originally eked out a humble existence as a street urchin on the streets of Belgrade before being lured into a "Program" run by ex-KGB agents to create assassins for hire for profit. However, she escaped from their governance and went on to hire herself as an assassin for hire, eventually falling into the employ of crime lord Julius Montferrat. There, she encountered James Bradley, and the two fought for some time before the former eventually defeated her by playing her right into his hands. Grudgingly, Karina helped James defeat Julius Montferrat and save the city.

At that point, she would have left the city if James hadn't roped her in with promises of financial backing if she trained him, and reluctantly she accepted. While doing so, she began a relationship with James' cousin Pam, a relationship which served to tether her to the "good side" as the Doylist perspective goes. She fought by James Bradley's side during the Battle of Wickham and eventually, developed a sort of caramaderie with the idealistic attorney, despite her very different outlook on life. Later, she and James and two others would form the group known as the "Wickham Four", after the city where their experiences were formed.

Then one day, she and the rest of the Wickham Four discovered the thing known as the "ATL Meetup", and they would get plunged into a bunch of wacky adventures across the Multiverse that they, unless like the rest of the Meetup, don't really enjoy.

Also at some point Karina became a Godly Being.
