The year is 2297, and ever since the Enclave was nearly destroyed, the wasteland has gotten worse. Elder Lyons was killed by a surviving squad of the Enclave seeking to give the Brotherhood of Steel what they deserve. After that, there was a civil war in the Brotherhood over who would be their elder, Sarah Lyons or the Lone Wanderer. Sentinel Lyons won after the Lone Wanderer was slain. Under her command, the Brotherhood became a shadow of what it once stood for on the East Coast...

The Brotherhood of Steel started to do what the West Coast Brotherhood did, gather tech. However, the new elder planned to use this tech to stop the "uglies." With her in command she made an army of robots to fight alongside the knights and paladins. They gained newer tech, they stole the power armor the enclave used and the plasma weapons and started to use those.

As Lyons' Brotherhood of Steel grew in power, so did their corruption. As they got tech, they stopped just killing super mutants and continued to kill ghouls, and even wastelanders that had a visible mutation, like a sixth finger or a third eye. After a wastelander named, "Bryan Wilkes," discovered this, he headed up north to the state of "Maine."

Once he finally arrived, he managed to let the Knights of the Rose know of the actions of the Brotherhood of Steel. Bryan became the spy and harbinger which would bring the fury of the Knights of the Rose. The Knights of the Rose were an elite organization of highly-trained warriors and marksmen. Armed with plasma rifles, trench knives, and plasma pistols they were to be feared. Protected by T-51B Power Armor, they were like walking tanks.

Now they are coming, the Brotherhood of Steel is in danger, which side will you serve?

Ahh so the BoS becomes the Enclave. WHAT IRONNNNNNNYYY. I like it.
