Now that we've uncovered the truth behind the Terrormorph attacks and their source, it's time to tell the truth to the Cabinet. You also get to make one of the most important decisions in Starfield, the fate of Vae Victis, and what happens to the Terrormorphs in the UC Vanguard Quest A Legacy Forged.
A Legacy Forged Walkthrough
Speak to Vae Victis
Head to New Atlantis and go to the lift in the MAST Building. Head down to Sub Section Seven and speak to Vae Victis in his cell. He'll deny your accusations but admit to it once you press him a bit. He'll try to justify his actions and convince you to keep his involvement a secret. In return, he'll offer you some quests once you're done.
Speak to Hadrian and Percival
Head back up to the Cabinet Chambers and speak to Hadrian and Percival. They'll ask you about the culprit and discuss the options for dealing with the Terrormorphs and Heatleeches.
Lie About Vae Victis (Optional)
If you tell them about Vae Victis, they will inform the Council and have him executed or removed from his chamber. However, if you keep his involvement a secret and blame Orlase, Vae Victis will retain his position and assign you some quests later. Your companions don't have to know, so besides your morals, it's a better choice to take Vae Victis' side.

Speak to the Cabinet
Speak to the Cabinet, and they'll commend you for all you've accomplished. This is the last place where you can choose to come clean about Vae Victis. Afterward, the Cabinet will ask you which Terrormorph solution is more effective. Lastly, they'll grant you Class One citizenship in the UC and finish the quest.
Choose the Probe or the Aceles
Choosing between the Probe and Aceles is pretty much the same. However, it will give you a different cutscene moment during the final quest, One Giant Leap. This choice also alters the ending you get slightly.
