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.

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.

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.

The quest Oasis can be completed in several different ways. (Spoilers ahead)

When you approach the Oasis Tree Father Birch (Apparently the leader) will flag you down and begin talking to you. He will inform you that "He" wants to see you. You are lead inside where you are then instructed to drink some sap. The sap knocks you out and you wake up inside a 'room' that connects off of the main area. This area is called The Grove, and this is where 'He' resides. 'He' turns out to be Harold from the previous games, now a full tree.

Navigating your way through the dialogue tree lets you learn that Harold wants to die. This gives you the quest, "Oasis". There are several ways to finish this. Bob tells you that he's "all spread out" and that some of his organs must be underground. You can find his heart below in a cave. To find the cave, return to the area where you drank the sap and head left. You will see Birch and his wife arguing. They will give you two more options on how to kill Bob which will be discussed later. Talk to Cyprus near the cave entrance, he will give you a key to the cave. Enter the cave. You will find a dead branch tender, you can loot him to take his outfit. Be careful, there are several Mirelurks and even a Mirelurk king further on in the cave. The water is also radiated. When you get to the part of the cave that is open and there is a massive (relatively) body of water, you must navigate your way through the water to reach the Sunken Caverns. The only way to get through the cavern with the water is to go under and through a tunnel, it is difficult to find I apologize.

When you find your way through the sunken caverns you will hear Harolds heart pumping. Now is the time to make your choice. You can either kill Harold, or activate his heart to put one of two ingredients on it, either increasing or decreasing his growth. Killing him makes your skin as tough as bark (perk) and no karma either good or bad. There is a door to your right that will lead you outside rather quickly, but prepare for a fight with more Mirelurks. When you are outside, speak to Birch to finish the quest. None of the Treeminders will be hostile towards you.

Applying either the sap or the ingredient that helps him grow will not give you the tough as bark perk, and the treeminders will not be hostile towards you. You will not recieve any karma for any of the deeds except for the last option, which brings me to my next point:

There is an incredibly evil way to finish this quest. Speaking to Harold (Or the little girl outside will with a successfull speech roll) will reveal that Harold is afraid of fire. Using a flame thrower on him (Not the heart) will kill him and give you evil Karma. The Treeminders will turn hostile towards you.
