Oasis

For the quest with the same name, see: Oasis (quest).

The Oasis is a place somewhere in the Capital Wasteland that is unusually full of trees and other green plants.

Location
Oasis is situated almost at the top center of the map, near the "Cliff Top Shacks" and directly NW of it by about one square. It is surrounded by steep cliffs, and can only be entered through a small gorge from the west. You can also find two ghouls hovering over the corpses of two escaped slaves. If you make a speech attempt, they will give you the water in the nearby refrigerator. Otherwise they'll attack.

It is possible to get the coordinates of the Oasis by killing the Drifter at Dickerson Tabernacle Chapel. There are also a pair of wandering wastelanders who will disclose the location, before attempting to kill the player.

There is a Lone wandering merchant who speaks like a man posessed who can give away the coordinates before collapsing and dying. He appears to be a random character and has appeared in the farmhouse northwest of Vault 101, in front of the building directly across from the Arlington Library, and various other locations.

History
Harold, a special FEV mutant with a tree on his head which he called Bob (and now calls Herbert because, "Bob hates it"), eventually found himself overwhelmed by it and became rooted to the ground during his travels in the Capital Wasteland region. Here he was discovered by several people who began to worship him as a god, and a small and exclusive cult known as the Treeminders began to form in secrecy. Bob began to blossom (which he apparently finds embarrassing) and many plants grew in this area, which became green with life, a stark contrast to the outer wasteland.

A Vault 101 Dweller arrived and was urged to talk to Harold. Harold revealed his true identity, and begged for mercy; after being stuck in the same position for decades he was eager for death. The other dwellers of "Oasis" ignored Harold's wishes so far, and asked the Vault 101 Dweller to instead either suppress or expand Harold/Bob's fertility.

Quest
In Oasis there is only one quest to take care of. Speak to a man named Birch, he will inform you to drink the sap from a tree stump.

You will now be forced to listen to some dialogue while everything around you becomes hazy. You will wake up in a different section of Oasis with a tree in front of you, walk around it and talk to the tree.

Harold will inform you that nobody at Oasis listens to what he really wants and asks for your help. Harold had a tree growing on his head (Named Bob), and it eventually took root on his head. He says that the roots of the tree have moved, taking his heart away with it. It is up to you to locate his heart and follow his wishes... Destroying it! You are now able to go back into the beginning section of Oasis via the locked door. Follow your marker and you will encounter Birch and his wife discussing why you are here.

Birch wants you to rub the sap from the tree onto Harold's heart to purify it while Laurel wants you to Linament onto it.

Speak to the guard in front of the door and he will give you the key to the door.

Now comes the fun part...ish...

You will go through numerous sections within a cave, and encounter many Mirelurks, Mirelurk Kings and Mirelurk Hunters. Power through all of these (takes a little while as there are a lot of them and they operate in packs), then you reach the heart. Do whatever you wish, I chose to destroy the heart (no bad karma given). You will then enter another room where two Mirelurk Kings and a Mirelurk are waiting for you. Thankfully you are on a ledge above them so it shouldn’t be too hard to pick these guys off. Jump down and exit by going underwater through a door.

You come out in the 2nd section of Oasis where you met Harold for the first time. He is now dead (depends what you do I guess) and you are welcome to leave Oasis.

Nobody tried to attack you or has any hatred towards you for killing their "god".

Also the three choices you have and relevant rewards are,

If you decide to "Apply Laurel's Liniment to accelerate Harold's growth", you get Linden's Outcast Power Armor (Big Guns+5, STR+1, AGL-1, Rad Res+10) when you talk to Linden, and Poplar's Hood (Sneak+10, AGL+1) when you talk to Poplar.

If you decide to "Destroy Harold's heart", you get the Barkskin Perk. "You've been exposed to Harold's mutation and your skin is now as hard as tree bark". You also gain 300XP.

If you decide to "Apply Birch's Sap to stop Harold's growth" you get a missile off Cypress, your also told you will get a gift off Maple but I couldn't find him/her? i think i saws maple outside oasis shes the guard good luck
