Apologize for keep generating low-quality topics. Anyway I found this forum is apex!
So far I haven't seen Styg and Corp's attitude towards fanmade fiction or other products based on Underrail, so if there was restrictions plz contact me and I'll remove this topic.
-SPOILERS AHEAD-
As we've seen in the game, Wyatt's description of that "plasma cell" guy suits Ezra so perfect. After joining Oculus the player character could get information about Occulite's action, specifically, their service. Even Tanner asked for their help. (Consider that Godmen always use minions to reach their goals, this might be an ordinary fact)
Let me get this straight: it has been promising for ended-game player character to order an inside-assault from occulites, neutralizing & capturing Ezra and prepare for an interrogation, expose tons of secrets. I don't know what kind of payment they want 'cause you can't order a Oculus service in actual game, if it's charon, things would be easy. Otherwise maybe you can share your knowledge of Deep Caverns, combat, old Biocorp or even supersteel, based on your preference.
According to the background and game lore, if you choose to retire at SGS you have entered council and took the place previously belongs to Tanner. As game intro displayed, you are in charge of testing new applicant managing to join SGS. It's relatively easy for you to help occulites infiltrate this society, hence many chance for them to reach Ezra without suspicion.
Based on in-game mechanics, Ezra is not immune for stun and incapacitation, but not sure whether he have LoC and once it's positive, it might result something really bad. Additionally, he is the only one who wields secret thought control tricks in south (or all) Underrail. E.g. creating illusion spaces to trap people, (presumably) projecting pseudo item for another shape. Khazum Morakht whisperers are the best choice for kidnapping Ezra (with powerful thought control skills, especially psi inhibition) but I seriously doubt whether it's possible because these warriors are obliged to protect Oculus, not doing some Occulite task, so maybe the character need some northerner help. Not to mention if the preparition was all done, more than one psionic joining SGS would trigger suspicion from Pasquale (since every outsider have to pass physical examination before entering SGS).
Despite those troubles, once the kidnapping was done, you should choose a proper location for later movements. Cause a really bad blackout (with high hacking skill and full access in whole station), make Harold worry about recovery, then head to Junkyard with jet ski (better avoid Svana). I think if you've been keeping a good relationship with Scrappers they will let you carry some sensitive cargo into Depot A, or with the aid of some charon, and Wyatt is an important witness. Gorsky (if you helped him forming Silver Hands) might help if you tell him all the truth (selectively) but the trip to Core City is much longer.
Give me advice and more crazy ideas!
