As per the next few days, I will be a tad busy. But a brief synopsis of what my idea for the BoS Chapter was is this:

They took in some of the outcasts from the Mojave, a few years ago, but are mostly the original members of a very small chapter in Washington that was sent out by High Elder Jeremy Maxon in 2225 to head to the local area and search for anything of use. They, after the NCR-Brotherhood War, also seemed to take a turn towards the same doctrine as the Capital Chapter, and began providing safety and protection to locals, opened a small clinic, and even began teaching local tribes and villages to read, write, and even the basics of mathematics. They are very small in number, and would technically be considered Outcasts as they are against the Brotherhood's original purpose, but consder themselves a true chapter, nonetheless, and have accepted some of the "mojave outcasts" into their midst because they are Brothers.
