Orion Moreno was a soldier that used to serve in the Enclave in Captain Judah Kreger's squad at Navarro with Cannibal Johnson, Dr. Henry, Daisy Whitman, and Arcade Gannon's father. He was often in conflict with squad-mate Johnson over "philosophical" differences. Orion was a loyal soldier to the Enclave, never questioning orders or the legitimacy of the Enclave.
Some time after the destruction of the Oil Rig, and the NCR attacking Navarro, he, the squad, Arcade Gannon's mother and a young Arcade Gannon fled south into the NCR. The fall of the Enclave hit him hard. Arcade remembers him saying "Kiss America goodbye, boys," as they escaped Navarro. They continued to flee east as Enclave personnel trying to integrate into the NCR were being found. He and the squad eventually settled in the Mojave Wasteland and went their separate ways. Currently, he lives in a house near the NCR Sharecropper Farms, still holding a grudge against the NCR for what happened at Navarro, a situation not helped by accusations that he is squatting in NCR territory.
Like the other remnants, Orion has high health, greater than or equal to that of most companions. This, in addition to the high Damage Threshold provided by his armor, makes him something of a boss character and the fight is very difficult at lower levels. He can also use Stimpaks, a rarity among hostile non-player characters.
If you fail his speech check, and attempt again to "talk things out" he will say "We just did. Time for talking's over." a nod to Frank Horrigan from Fallout 2.
Orion's word for the Remnants bunker is "Remember."
Killing him results in no Karma loss, but will immediately fail the quest For Auld Lang Syne.
"Change of plan - you'll find that I've sealed the doors to this hangar - I don't want my friends getting involved in our little disagreement. Once I'm done with you, I'll talk them out of this stupid plan. You've opened some old wounds - it's only fair I return the favor."
"All right, then - I'll show up at this gathering of yours. It might be good to see the others - Johnson excluded. Arcade might've mentioned there's a pass phrase needed to get into the bunker - my part is "Remember.""

pcps3 He can be found wandering around Gypsum Train Yard without any items equipped, although he has a Gatling laser, Remnants power armor and Helmet, some Electron Charge Packs, and 3 stimpaks in his inventory. These items can be pickpocketed but will not appear on his corpse if he is killed. If this occurs, he can still be found in his house, so the side quest For Auld Lang Syne is still completable if the other requirements permit. [verified]
