Oasis

The Oasis is a location Northwest of Clifftop Shacks 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.
 * The entrance to the gorge is directly north of Broadcast Tower LP8, west and slightly north of the Oasis Marker placed on the map by the Drifter's or Wastelander's notes.
 * 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 the car and face west. The letters "CMR" are visible on the side of the car. Behind the player will be a pile of highway debris. Turn around and proceed east over the pile of debris. There will be a bridge over a gorge. Crossing the bridge and following the path in a generally easterly direction will lead directly to Oasis.

This link has four pictures - position yourself where the pip boy shows you and you will see the bottom left picture - go straight ahead following the path and you will find it in around 10 seconds of walking.

If the player has progressed far enough in the main quest, he or she may encounter an Enclave outpost under the bridge. dropping grenades into the gorge will root out the targets, or cause them to run out of the gorge towards the player where they can be picked off one by one.

It is possible to get the coordinates of the Oasis by killing the Drifter at Dickerson Tabernacle Chapel. There are also a pair (or more) of wandering Wastelanders found in a random encounter 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 (Sometimes calls it 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.

When the Lone Wanderer arrived he/she 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 had ignored Harold's wishes thus far, and asked the Lone Wanderer to instead either suppress or expand Harold/Bob's fertility.

Quest
As soon as you are at Oasis, the leader will approach you. Following him, you'll go into a ceremony. After this ceremony, you are allowed to speak with Harold. When you speak with him, he will ask for you to kill him. if you talk with him enough your quest will be updated with a new option. The new option will be to burn Harold down, if you do you will gain bad karma. This is an easy way to complete the quest quickly if you wanted to save, burn Harold to complete the quest, and then reload your last save if you want to save this quest for later on.

Oasis Caverns

 * Ever wanted to dress up like a branchtender but you don't want to kill one to get their clothes? Then be sure you don't miss the dead branchtender about 50 feet inside the Oasis Caverns main doors (he's right by the lantern). Now you can sport a Oasis Villager Robe just like Branchtender Linden and his ilk.

Nearby Factions

 * Outcasts can be spotted patrolling fairly close to the Oasis. It is unclear why the Outcasts would be traveling in this area since the Treeminders forsake technology. A possible reason is that they may be a search party out to look for Branchtender Linden (a former Outcast member) and the rest of his squad, if only to recover their weapons and armor in accordance with their desire to retain their technology- the general northern region of the Capital Wasteland is also home to several satellite arrays, a vault, and a military base.
