A warehouse somewhere in Night City.
At 2 m and 140 kg Mishka was a large bear of a man with enough cunning to make a name for himself in the pits of Vladivostok. Unfortunately someone had heard of him and decided that he could better serve the Motherland harvesting chrome from capitalist pig dogs, and so they had arranged for him to be smuggled into Night City where he now waited to meet his handler.

A tall thin man with a skinny face and pale skin steps from the shadows to greet Mishka.

"Здравствуй I am Nikolai and I arranged things for the Motherland in this miserable city."

"Mishka" the larger man grunted by way of reply.

"Ha" the skinny man chuckled continuing "I'm told you already know why you're here so that just leaves telling you the rule for operating in Night City."

"Rule number one" said the thin man raising a finger. "Make sure your target won't be missed by anyone important. If the locals decide to pay for a recovery job their are dozens of mercenaries that will happily assault your base."

"Rule number two" the pale man continues a second finger joining the first "Beware the Corporations they are disgustingly powerful in this cursed city and respond violently to even minor irritants."

"And most importantly Rule 3" said Nikolai staring into Mishka's eyes wit sudden intensity. "DO NOT antagonize Дева Яга."

Mishka blinked "Who is this Дева Яга"

Nikolai face grew grim as he replied. "We still aren't quite sure. A few years ago cells started going dark suddenly, no cries for help, no survivors, no escape.
When someone would investigate they would find everyone dead and all their product gone. Occasionally their would be signs of a scuffle but never much clue who did it. A few months after that one of the copycats tried to kill a Tiger Claw kill borg in his apartment and over the next week 75% of the cells and copycat gangs in the city were wiped out."

"Surely" Mishka interrupted " that was just the Tiger Claws making a point about attacking one of theirs at home not some witch child."

"You would think" Nikolai responded glaring at the interruption "but the Claws couldn't reach most of the cells bases without kicking off a gang war with one of the other gangs in town. About 70% of the cells that went dark that week looked like the cells that had been going dark for the months leading up to that week. Just corpses the chrome had been left but that was the only real difference. Who ever did this released a series of XBDs depicting the clean up a month or so later detailing the attacks. It seems to have been a single terrifying young girl. She still occasionally takes her dur visiting a cell and leaving nothing but corpses in her wake. The last time a cell tried to save another cell every cell within a mile went dark the next day. Mishka if you want to live DO NOT antagonize Дева Яга because if you do You WILL die if not from her wrath from mine."
