You're standing in the middle of Red Rock Canyon, surrounded by bikers who look like they stepped straight out of a post-apocalyptic Caesar's Palace. The Great Khans have a problem. Or rather, their leader, Papa Khan, has a problem—he’s about to sign a suicide pact with Caesar’s Legion, and he’s the only one who doesn't realize it. Oh My Papa New Vegas is arguably one of the most complex, frustrating, and rewarding quests in Fallout: New Vegas. It’s a tangled web of political maneuvering, stealth, and high-stakes diplomacy that perfectly encapsulates why Obsidian’s 2010 masterpiece still holds up over a decade later.
The Khans are a proud, broken people. They’ve been kicked across the Mojave, from Bitter Springs to the outskirts of the map. Now, Papa Khan wants revenge against the NCR so badly he's willing to ignore the fact that the Legion doesn't take "allies"—they take slaves. Your job, usually at the behest of the NCR or because you just happen to like the underdog, is to break that alliance.
It isn't easy.
The Brutal Reality of the Great Khans
To understand why this quest matters, you have to look at the history of the Khans. They aren't just "raiders." They are the remnants of Vault 15, a group that has been destroyed and rebuilt three times over. By the time you find them in Red Rock Canyon, they are drug runners with a warrior culture, clinging to a sense of identity that is rapidly eroding.
Papa Khan is stubborn. Honestly, he's a bit of a jerk. He’s blinded by his hatred for the New California Republic after the Bitter Springs Massacre—a traumatic event where NCR snipers mistakenly fired on Khan non-combatants. You can't really blame the guy for being mad. But his anger is leading his tribe into extinction.
The quest Oh My Papa New Vegas requires you to prove to Papa Khan that the Legion has no respect for the Khans. You have to find evidence. You have to talk to his advisors. You have to convince the "four pillars" of the tribe—Regis, Jack, Diane, and Melissa—that their future lies elsewhere.
How to Actually Complete the Quest Without Killing Everyone
Most players stumble into Red Rock Canyon and realize they can't just talk their way through the front door. If you want to finish this without a bloodbath, you need a high Speech skill, but more importantly, you need a bit of detective work.
First, talk to Regis. He's the second-in-command and the only one with his head on straight. He knows the Legion deal is bad news, but he won't move against Papa without proof. This is where the quest gets technical. You have to head to Cottonwood Cove or Caesar’s Fort and find the "Legion Ledger." It’s a literal paper trail. It explicitly states that the Khans will be integrated (read: enslaved) into the Legion once the NCR is defeated.
But proof isn't enough for the whole tribe.
Convincing the Inner Circle
You have to go on a bit of a world tour.
- Melissa: She’s out at Quarry Junction (good luck with the Deathclaws). She’s waiting for a shipment of supplies from the Legion that is never coming. When you show her the truth, she flips.
- Jack and Diane: The resident drug brewers. They don't care about politics; they care about business. You have to convince them that the Legion's strict anti-drug policy means their heads will be on pikes the moment Caesar takes over.
- Regis (Again): Once you have the ledger and the support of the others, Regis will help you corner Papa Khan.
The Bitter Springs Connection
You can't talk about Oh My Papa New Vegas without talking about the trauma of Bitter Springs. If you bring Boone along, things get tense. The game forces you to reckon with the fact that the "good guys" (the NCR) committed a war crime.

This is the nuance of New Vegas. There are no clean hands. To convince Papa Khan to break his treaty, you sometimes have to acknowledge that his hatred is justified. You can't just tell him the NCR are the heroes. You have to convince him that the Legion is simply worse. It’s a choice between a slow death by assimilation or a chance at a new beginning elsewhere.
What Most People Get Wrong About the Ending
There’s a misconception that there is only one "good" ending for this quest. That's not true. New Vegas loves its shades of grey.
If you convince Papa Khan to break the alliance but don't give him a new purpose, the Khans might just wander off and die out. However, if you find the ancient Mongol-inspired history of the Khans (located in the followers' outpost or via certain dialogue trees), you can inspire them to leave the Mojave entirely.
They head north. They settle in Idaho. They carve out an empire that actually lasts.
It’s one of the few truly "hopeful" endings in the game, but it’s buried under layers of dialogue and exploration. If you just kill Papa Khan and put Regis in charge, the Khans become an NCR vassal state. Is that better? Maybe for the NCR, but it’s the end of the Khan culture.

The Technical Hurdles
Let’s be real: this quest is buggy. Even in 2026, if you're playing the original version without community patches like YUP (Yukichigai Unofficial Patch), things go sideways.
Karl, the Legion envoy standing next to Papa Khan, is the biggest variable. You can bait him into insulting the Khans in front of the entire longhouse. If your Speech is high enough (usually 75), you can make him lose his cool. Papa Khan will then have his guards execute Karl on the spot. It’s a satisfying moment, but if you trigger it too early or in the wrong order, you can break the quest script entirely.
Always save before you enter the Longhouse. Always.
Why This Quest Still Matters in 2026
We don't see writing like this in modern AAA titles very often. Oh My Papa New Vegas doesn't use quest markers for every single step. It expects you to listen. It expects you to care about the internal politics of a group of fictional bikers.
The quest is a microcosm of the entire game's philosophy: your choices have weight, but they are limited by the material reality of the world. You can't make everyone happy. You can't "fix" the Khans' past. You can only steer their future.
Actionable Insights for Your Next Playthrough
If you're jumping back into the Mojave, keep these things in mind to get the most out of the experience:

- High Speech is a Cheat Code, But Exploration is Better: While a 75 Speech check can end the quest quickly by taunting Karl, finding the Legion Ledger in Caesar's tent provides a much more narrative-heavy resolution.
- The Great Khan Armory: Once you're in good with the tribe, Diane will let you use their armory. It’s one of the best places in the game to buy bulk ammunition for a discount. Don't blow your reputation until you've stocked up on .308 and 5.56mm.
- The "Infiltrator" Approach: If you’re playing a stealth build, you can sneak into the Longhouse and plant the evidence without ever speaking to Papa Khan initially. This changes some of the dialogue triggers later.
- Check Your Reputation: If you have "Vilified" status with the NCR, completing this quest becomes significantly harder because you can't access certain NPCs who provide the historical context needed for the "Empire" ending.
- The Idaho Ending: To get the best possible outcome, talk to Ezekiel at the 188 Trading Post. He’s part of the Followers of the Apocalypse. This is the key to giving the Khans a future that doesn't involve them being meat for the grinder in the Second Battle of Hoover Dam.
The beauty of New Vegas is that the world doesn't revolve around you; you just happen to be the person with the gun or the silver tongue who tips the scales. Whether the Khans become a footnote in history or a rising power in the north depends entirely on how much legwork you're willing to do in the dust of Red Rock Canyon.
To truly master the quest, you need to stop thinking like a player completing a checklist and start thinking like a diplomat in a war zone. The Ledger is in Caesar's tent, specifically in a footlocker. Sneak in, grab it, and show the world that the "Mighty Caesar" is nothing more than a slave trader in a fancy toga. That's how you save a tribe. That's how you finish the job.
