"When Alexander saw the breadth of his domain he wept, for there were no more lands for him to conquer."
I hit this exact same wall, I completed every quest and visited every location. Got to lvl 30 and returned to Megaton to stash the last notable loot. Then I stopped, looked out over the walkway and just watched people go about their lives for a while. Then I realised, there is nothing for me to do in this game anymore.
Saving the game, I turned it off and thought, what shall William (my characters name) do now? I always toyed with the idea of him wandering west to find a new adventure but then I thought, no. My character had become like The Doctor, a mythical figure that appears in the hour of need and saves everyone. The Lonely Angel walking the ruins of the Old World. Instead I decided William was going to do what he had always done, Survive and Thrive. But this time he would take it one step further, he would revive the wasteland.
Travelling to Rivet City he mustered the council and proposed the idea of a proper nation, creating a connection between Rivet City, Megaton, Arefu, Cantebury Commons and many other locations in the Captital Wasteland. Setting himself up as the self-styled 'Governor' William created teams consisting of Mercenaries such as Reillys Rangers and Talon Company (with their leader dead they had no choice but to obey William). The Regulators, Brotherhood of Steel and Rivet City Security. Raider bands could earn their pardons by joining the ever growing 'Captial Guard' and its helpers. They were armed and equipped with the best arms and armour Money could buy (taken from Tenpennys funds) they conducted a huge sweep of the Capital wasteland. From every Metro Tunnel to the high rise buildings still standing, Ghouls and Mutants were cleared out. Uncooperative raiders forced to surrender or die (after early successes many joined up anyway) medical and production equipment was gathered up.
Using the now clear D.C. Ruins William set up camps and structures, more solid and clean than those in Megaton. Where possible old buildings were cleared out and repaired so they could be lived in again. Settlements in the Wasteland were offered the opportunity to join the growing nation, with food, safety and clean water (remember the purifier) they flocked to join. figures such as Ernest Roe managed trade caravans between settlements to be well defended and the settlements flourished.
Returning to Adams Air Force Base with a team of scavengers William stripped the place bare, Vertibirds were taken, weapons and ammunition stockpiled and the twisted metal remains of the base itself carried piece by piece (by vertibird) to the wasteland to provide even more raw materials. Using his foundries at the Pitt William began manufacturing products, rather than scavenging the old he made the new. Habitable vaults such as Vault 112 were cleared and repurposed as homes. Older vaults were cleared such as Vault 94 and 108. They soon became hospitable again. Using the surviving books and resourced from Pre War books in the vaults people became doctors and scientists. During this time Vault 101, which allowed trade with the outside world, remained untouched on Williams orders. However, a message came that Alphonse Almodovar and many of the older members of the vault had passed away and with them gone, hate for William had died down. Vault 101 opened its doors fully to the outside world and William married Amata at the Rivet City church. He continued to rule the Capital Wasteland for years, guiding it through times both difficult and prosperous such as when Brotherhood outcasts firebombed a Brotherhood defended caravan causing tensions to rise to the point of a war. Instead, William offered them an Ultimatum. Either the Outcasts leave their base and are allowed to take all their technology west, back to the brotherhood or soldiers armed with Fatmans and Experimental MIRVs would bombard the place. Unsurprisingly the troublesome outcasts packed up and left.
Years later at the age of 64, William chose his eldest child to succeed him and taught her how to defend and manage his country. He and Amata retired to Vault 101 where they would live for another 17 years. William died first, and Amata only a few days later. They were buried outside the water purifier with a huge Vault Door from Vault Tec HQ (it says 101 on it) as the entrance to their tomb.
When Williams daughter died at the age of 72, her son took over. His name was James. In honour of a brave man who set forth from the comfort of his home to try and save the world.
