The branch he put his weight on snapped and the Courier fell a short distance to the ground, managing to catch himself on a lower branch. Muttering a curse under his breath, he questioned why he was attempting to do this. 'Oh right, the only other damn way in I've managed to find is to swim in the ocean an unknown distance,' he thought as he continued to climb towards the elevated rail that had an entrance through the wall. Admittedly, that entrance was a sealed door, but the Courier hoped to be able to find a maintenance door or something.
'Why the hell do they even need a wall this large anyway?' the Courier continued as he ascended the tree that was relatively the closest to the rails. 'Defense? Against what? There are a numerous other ways far cheaper to defend against another nation, and I haven't seen any wildlife out here anywhere that would justify this. Sure, there were those Yao Guai lookalikes but New Cal' hasn't had to build something like this and we deal with fucking Deathclaws. Maybe there's something bigger out there I haven't seen yet...'
When the Courier became level with the elevated rail, he heard a slight hum. He was confused for a second, before recognizing the sound. 'Rails must be electrified. Better be careful where I land.'
After testing a branch that was the closest to the rail line, the Courier ran along it. He heard the branch strain and lept to the elevated line as the branch snapped. He narrowly gripped the edge of the platform with his right arm and carefully proceeded to haul himself up, careful not to touch anything metal. The electricity could accidentally set off some of his bullets or custom explosives by accident.
The Courier slowly walked along the tracks, careful not to come into any contact with the rails humming with electricity and came to the wall after a relatively short period of time. Walking along the doorway, he found a small, fairly broken platform off to one side. Walking onto it, the Courier found a door with a old keypad heading into the wall. 'Maybe it's for maintenance? Whatever, let's crack it open.'
The internals were a bit more advanced than what he had seen within the Wasteland, but not to a massive degree. The keypad was unpowered, but use of the battery within his helmet's light solved that problem. After a few minutes of work, the Courier managed to get the door to unlock. Just before entering, the Courier put on the Stealth Boy, as a just in case measure, and replaced the battery of his helmet's light.
A quick look inside caused the Courier to judge that while it had been used recently, but was likely not a regular route. The Courier activated his helmet's light and closed the door behind him, resolving to just use a Nuka grenade if he needed to go back through there and nothing inside worked. He made his way down the short corridor, and, when arriving at the door, turned off the helmet's light. Carefully opening the door and seeing it was dark, the Courier reactivated his helmet light and entered the room.
He found himself within what he guessed to be a customs office of a sorts, though long abandoned. The room had some windows on the rail side, and, upon looking through them, the Courier noted that they looked into the passage through the wall, the large doors to either side. A search of the office turned up nothing immediately useful, but allowed him to deduce that this had likely been here before the rails were constructed.
'Just how old is this wall?' the Courier thought as he finished his search of the area. 'And was this place build during its construction or after? Furthermore, did that elevated rail exist before the rails? Geh, not going to get any answers sticking around here...'
The Courier continued through the door on the opposing side of the one he entered through. The corridor on the other side was slightly shorter than the former passage, but not by much. After shutting off his helmet's light, he opened the door that would open out to the other side of the wall. After properly adjusting to the dark, the Courier found the platform had fallen away on this side, but off to the side there was a ladder that reached most of the way to the ground. While he might be able to reach it, the Courier decided to save the descent for when the sun was beginning to rise rather than in the dead of night. Besides the low level of vision, he was starting to get a bit tired, and he believed his allotment of luck for the day was getting low.
Returning to the office, the Courier set his duffel bag against the wall and sat down next to it. The Courier logged the events of the day in his Pipboy so he could provide the Think Tank back home with a record of events that occurred during his time. After that, he set the timer for the Pipboy to wake him in a few hours and let sleep take ahold of him.
This one is a bit of a short chapter, but you underestimate how many times I had to restart in order to get an idea of exactly how to get the Courier inside the walls without needing him to run into either Ozpin's or Cinder's factions. You may be wondering why. Well, I wound up having a few different paths the story could go down, and asked someone on Spacebattles to pick a number to see which would be utilized. Wound up with one of the Wild Card (ie. not initially allying with Ozpin or Cinder) routes. Whether he will remain unallied to either faction may change further down the line, but for now the Courier will forge his own path.
