|How to Start:||Read a Terminal near Sublight Storage on the Promenade|
Interact with a terminal on the Groundbreaker's Promenade near the Sublight Salvage facility and read the entry [Seeking Contractor: Sublight Salvage], which tells "ethically-flexible" spacers with Stellar Bay landing clearance to seek out Lilya Hagen for a job opportunity. You'll be able to start this quest after you buy the Stellar Bay Navkey from Gladys or after you complete the quest Long Distance and get such a navkey from Akande.
With this key in your hot little hands, enter the Sublight Salvage facility, ride the elevator and enter Lilya Hagen's office. Here you will, of course, find Lilya Hagen. Talk to her and tell her you have a Stellar Bay Navkey and she'll offer you the job with little further fuss. Seems one of her men had a lead on some "high-grade salvage", and she needs you to go find out why he went missing. She'll suggest you look for clues around the saltuna warehouse, then talk to Catherine in Fallbrook. Exhaust her dialogue options if you wish to learn more about SubLight's business on Monarch, Monarch itself, and exactly what "high-grade salvage" you're after. For accepting the job you'll gain some positive Reputation with SubLight and depending on what else you've done, maybe update the quest Weapons From the Void. More importantly, this ends Salvager in the Sky and starts Space-Crime Continuum, the latter of which is the first SubLight faction quest.
