Mod:Fallout: The Frontier/Lion's Den

Lion's Den is an NCR main quest.

Walkthrough
5,000 caps weren't enough. C-finder is actually found in Ostia and we were sent to retrieve it. You can pass as traveling merchant with speech 75, barter 60 or 500 caps for bribe for the first gate. To pass the second gate you have to equip gladiator armor just lying next to a tent and accept the offer to join the arena. The Constantine may show up (i got ww'd). third gate is only for praetorian guard. The praetorian guard are forming from winners of the arena so either that, or solo assault head-on. So you have 4 matches - against generic gladiator, a generic bighorner rider, the big meanie Hercules and the ncr greenhorn Private John. You can talk to him, but you can't fake his death (i think). Either you kill him, or the entire base will be against you.

Now you have access to outside area. To get the right to freely walk inside the castle you need to be examined by valerius himself. If you break in even with stealth boy, everyone inside and outside will turn red. And the servitus and st. someone line from some praetorian guard is also ww. You can sneak your way (there's a tree log on the side of the wall that can lead you up) in but beware of very hard locks and some individuals inside. Don't forget the Eviscerator MG. After talking with Marcus you have to kill him and his 2 bodyguards. While inside the room, you may want to steal 6 gold bars from dead money dlc, a bunch of legion pennies, a bladed glove, a legion centurion helmet, a bumper sword and some notes. Sneak 134 is enough to squat parkour inside before everyone's eyes.

The dungeon opens with 'Ostia Key' and the storage room in dungeon opens with Ostia Dungeon Key, where you can find c-finder, along with some legion armor, the Front Seat shotgun and the Hardcase's dogtag. Watch out for trip wire on your way to storage. You can find AJ and she suggests to escape through the well, you press 'break through' button and run toward the cave exit. At the end AJ starts to give up but you can talk her out of existential crisis with speech 70 or just sit next to here for a while. It's not like we're in a hurry, yknow. Outside you meet noname ncr trooper who came to rescue you with his buggy but after dialogue he gets his head blown-off. So you use buggy to drive under the bridge up until the collapsed part because legion artillery. After that, you get teleported to base and get the next quest Reign of Terror.

You may hand over c-finder, or keep it to yourself.

Bugs

 * After killing Private John the quest marker will not update meaning you will need to reload a save.
