First serie of ideas I have :
The Last dungeon : Vault 1 dungeon
Starting location : Broken hills, in an inhabited house.
Number of player needed : 3+
First part of the quest : killing 3 super mutant remnants that can be found near Necropolis-boneyard.
Player : Can you tell me anything about the world?
Robert Lang: When I travelled in my young age, I found many different places and things. Through my trips, I found something that might interest a group of traveler that are extremely strong.
Player: My friends and I are pretty strong, we can kill anything that comes our way pretty easily.
Robert Lang : You need to prove that to me, kill at least 3 super mutants remnants and come back to see me. Id hate to be responsible for your death.
Player: Alright, challenge accepted.
Second part of the quest : Finding a piece of the key that lies in the last floor in Ares, in mariposa and in The glow.
Player : We’re back and we’ve killed 3 super mutant remnants!
Robert Lang: I can tell you didn’t lie about your power! Very well, I will give you the details about that special place I once went and where I lost many good friends. (next)
Robert Lang: We were once in the desert and a huge storm was coming in front of us. We needed to stop somewhere to protect ourselves from the storm. (next)
Robert Lang: We went inside a cave where we found a strange room filled with armed robots that were protecting it. We had to flee, but not without locking the door behind us. (next)
Robert Lang: We separated the key in 3 pieces and placed them in 3 different locations that would be impossible to get. (next)
Robert Lang: Since you are strong and ready to go I will tell you the exact locations of the parts of the key. (next)
Robert Lang: One is located in the last flour in Ares, one is hidden in Mariposa and one is in The Glow. Good luck!
Third part of the quest : Getting the stuff from the dead bodies of Robert Lang friend.
Player : We are back and we found the three pieces of the key.
Robert Lang: I will show you how to assemble them if you give them to me (hand him the parts of the key)
Robert Lang: Now I will show you the exact location of the place where you can find my dead friends. Would you be kind enough to bring me their dog-tags? (Accept or refuse)
Players: Yes, we will.
Fourth part of the quest : The dungeon
The first body can be found in the first floor, the second body on the second floor and the third on the third floor.
Upon completion of the quest Robert Lang will give his old stuff that he used to use (Some good chances of finding bozar, unique enclave armor, etc.) To be thought about.
There is also loot in vault 1.
Once you have completed the three first part of the quest you can go back there as many time as you want. But the loot that is given by Robert Lang is given one time only.
P.s. As soon as I have confirmation from on GM I will start working the map.
PPS If anyone wants to give me some tips on mapper would be great!
