Įlijah's obsession with HELIOS One and the need to defend against NCR forces deploying into the Mojave resulted in the Brotherhood ignoring the expansion of the Van Graff family into the Mojave, despite them distributing pre-War energy weapons. The balance of power shifted in 2273 when a large contingent of NCR troops entered the region and occupied Hoover Dam. The Mojave chapter operated freely amid the Vegas wastes for several years, carrying out many reclamation missions without serious opposition. Elijah, already considered unorthodox for his focus on improving technology, rather than simply preserving it had ordered for it to be converted into the Brotherhood's headquarters despite objections from nearly every paladin in the chapter. The new chapter settled into the Hidden Valley bunkers, then rediscovered HELIOS One. As Elijah proposed developing new ethically questionable weapons somewhere around the early 2260s, the elders decided to send him away to the east, to form a new chapter of the Brotherhood in the Mojave.
Elijah, a scribe-come- elder, pushed for the development of new technologies, which put him at odds with the more conservative members of the Brotherhood. While officially sent out to secure Hoover Dam, the formation of the Mojave chapter was mainly a result of disagreements within the elder council. 3.1 Interactions with the player character.1.1 War with the New California Republic.
