Leave the office and take the elevator down to the P2 level. Talk to a miner named Andy at the Sixth Circle and ask him where you can find Percival.

Speaking to Lou the Bartender will give you information about where to find Percival. However, you will need to answer a few questions for him before that.
| "What is the Meaning of the UC Vanguard Motto?" | |
|---|---|
| Answer | Above and Beyond |
| “And tell me, what grade was it you got on your entrance exam? A? C? D‑plus?” | |
| Answer | The Vanguard entrance exam isn't graded like that. |
The UC Vanguard motto, Supra Et Ultra, means Above and Beyond. You can choose this answer when asked about the motto. There will also be a follow-up question inquiring about your results in the Vanguard entrance exam. You can also prompt Sarah to vouch for you if you have her on your team to skip this question and continue progress on the quest.

| Optional Objectives | |
|---|---|
| Kill the Spacer Leader | Change Percival's Debt Amount |
In exchange for Percival's location, you'll have to pay Oktai Enbayar with Percival's debt of 21,867 Credits. You can either settle this amount by killing the Spacer Leader or by accessing the Accounts Computer in the main level to reduce the debt to 1000 Credits.

You can find Percival in the deeper parts of the Deep Mines. You can get there by following the quest marker and using the Hand Scanner to track it. It might be a bit confusing to find so try to observe the path first and use the Hand Scanner from time to time. Once you've located Percival, hand him the tissue sample of his old colleague.

| 10 | ![]() After crossing to the other side, you will finally meet Percival! |

After speaking to Percival, follow him down the Laboratory area. He'll be analyzing the tissue sample that you gave him earlier.

Leave the mines to meet with Hadrian back at the Sixth Circle bar. You can quickly exit the area by taking the lift nearby to the surface using the Red Devils HQ key that Percival gave you.

Once you're back at the Sixth Circle, let Hadrian and Percival finish their brief conversation. Afterwards, follow them to a secluded area inside the bar.

Report to Hadrian regarding the situation back in the mines and how the delivery and analyzation of the tissue sample went. The quest ends after the dialogue conversation and you'll be tasked with meeting Hadrian in New Atlantis for the next part of the faction questline.
You have two ways to remove Percival's debt if you don't want to pay a whopping 21,867 Credits. You can either Kill the Space Leader in the Deep Mines or hack the Trade Authority to change his debt. It's better to kill the Space Leader in the Deep Mines as you can get a lot valuables and rare items.
Following this optional objective will take a lot more time to complete but will yield greater rewards. One of those rewards is the Pick-Me-Up Drug recipe, which increases your inventory capacity permanently. You can even get some Legendary gear if you're lucky!

This is the quickest method to settling the debt as you'll only need to access the Accounts Computer in the main level to reduce Percival's debt to a reasonably acceptable price of 1000 Credits.
To access the Accounts Computer, go behind the bar inside the Broken Spear and then proceed to the security room. After that, go down the stairs where you have to lockpick an Advanced level lock!
