You need to trigger the quest then
If you didnt trigger the faction war, you need to continue the history of black eels, also, you need to found the old man with 2 dogs in the deeps of depot A, he gave you some info(not sure if really need it for the history of black eels)
after that, you need to talk with SGS after you talk to Colton about the war.
At the moment, i'm not sure if you are betwen the faction war or if you already have trigger other events
Please, answer this questions:
How do you enter the worm hole?
*With colton trade favors ?
*With Scrappers help?
Do you already found the drill parts?
If you already do it
Go to Tanners office an continue de main plot, also
If you already finish the main part the next you need to do is talk to Silas, at some moment, he is goint to talk about some "job" he need to do, after that you begin the faction war.
If this help you, let me now
