Oasis

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. It is surrounded by steep cliffs, and can only be entered through a small gorge by traveling west to east. This gorge can be hard to find but is characterized by the following landmarks: - One square directly NW of the Clifftop Shacks - It is 9 squares to the east, in the northernmost row of squares on the World Map - There are several green shrubs on the ground and these are followed by small plants as you walk up the tiny gorge - There is a broken elevated railway/monorail line to the west - A random encounter can appear here.

How to find the gorge: Near the center of the north edge of the map, there is a road running parallel to a  railway line. Follow the railway/road until you find two abandoned railway cars. At the northern most railroad car, stand on the eastern side of of the car and face west. You will see the letters "CMR" on the side of the car. Behind you will be a pile of highway debris. Turn around and proceed east over the pile of debris. you will find a bridge over a gorge. Cross the bridge and follow the path in a generally easterly direction. This path leads directly to Oasis.

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 around the Meresti Trainyard who will disclose the location, before attempting to kill the player, as well as a dying Wasteland Merchant.

History
Harold, a special product of the forced evolutionary virus, 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 Harold 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.

Trivia

 * Harold's inconsistent naming of his tree is inherited from Fallout 2 where he jokingly refers to the tree as both Herbert and Bob.


 * Three Dog has apparently visited Oasis at some point, as he occasionally mentions "a place with lots of trees". However, he also explains that he had been "experimenting with jet" at the time, so before the player finds Oasis, it is unclear if the place actually exists or not.


 * Bob's appearance is similar to the Swamp Thing of Vertigo/DC Comics. The Swamp Thing was an earth elemental and was subject to the Parliment of Trees in the Alan Moore 1980's run of the title
 * There is a place called Green Valley near Washington D.C. which is fairly close to the spot of Oasis.


 * The Alley Preacher in Seward Square talks about trees to the north, a likely reference to Oasis. Interestingly, he states that the trees are in fact deadly; maybe because he has never seen actual living trees or actually a "living" tree.
