“Background Checks” is the follow-up Mission of “TOP SECRETS” for the Ryujin faction in Starfield. This is the step-by-step walkthrough.
After stealing the Project Dominon Files, the executive Masako Imada wants me to talk to Dalton Fiennes.

1. TALK TO DALTON FIENNES
Mission text:
“I need to find Dalton Fiennes in his office on the Executive Floor and see what I can do to help find the mole at Ryujin Industries.”
2. MEET NYX AT MADAME SAUVAGE’S PLACE
Mission text:
“I need to meet a person named Nyx at Madame Sauvage’s Place in Neon. He should already know that Directive Theta has been enacted.”
Follow the mission marker to Madame Sauvage’s Place. It’s one level down at Ebbside. Estelle Vincent (Nyx) is sitting inside, at ground level. You can either pay him 2500 Credits, Persuade him and do him a favour. Continue with this guide if you choose the favour, otherwise continue with Mission Point 3.

As favour, Nyx asks you, while you’re in the building anyway, to get information on Camden Cho from another workstation.
3. FIND A WAY INTO RYUJIN TOWER
Mission text:
“I need to find an alternate way into Ryujin Tower since Dalton said my access to the elevators will be temporarily disabled.”
4. RUN NYX’S PROGRAM ON ULARU’S AND CAMDON CHO’S COMPUTER
Mission text:
“I need to enter Ryujin Industries and run the program Nyx gave me on Ularu’s and Camden’s computers.”
You will only get the “Camden” mission point, if you picked Nyx’ favour option. His computer is on the way to Ularu’s, so I’m quickly covering them together.
If you have a companion, best to leave them behind. They shoot to kill and we don’t want that in this mission.
Now follow the short vent corridor you can open the vent again at the other end of the corridor to get inside the building.

7. RETURN TO DALTON AT RYUJIN TOWER
Mission text:
“I have the data that Dalton wanted as part of Directive Theta. I need to return to him at Ryujin Tower”
Head back to Neon Core and enter Ryujin Tower. Take the elevator up to Executive Offices to speak to Dalton. Hand over the slate and wait for his conclusions. He identifies Imogene as mole.
This concludes the Mission and the “GUILTY PARTIES” Mission starts.
