I find that there is no need to cultivate peaceful communities to the lawless north.
The south already has its own problems to contend with.
I would recommend that the Order move south where there is already a framework to use. You will get naught but criminal scum in the northern reaches. Its a lost cause.
The South has potential and needs help, help that you can provide if you reach out with acolytes at the HUB and other places like Junktown and maybe even the NCR.
Our Mines at Junktown are being desecrated by raiders groups of whom have been seen to operate there, having a watchful eye can be a breather to push for banning assaults on guarded positions.
I'm not against the idea of helping others at all you see, but I only lend my hand to those who've shown willingness and potential to learn.
Those of whom are willing but unable I lament to their plight, but I am almost alone in my struggles at the south.
With that said I've been able to construct a trade network across the world map that I can use to gather resources, as well as a modest stash of equipment by my side.
I require more vehicles however... I am still vulnerable. And I've taxed my resources to their ends to reach out and hand my Wasteland Survival Guide.
If you're here to help the wastes I encourage that you at least start here at the HUB, simply tell those who you see shoveling the wonders of other methods such as crafting, mining, even locker hunting, and cave diving.
Perks are important as well and education is vital. Central's Bid to aid the South was a lost cause, perhaps this Project may have a bit more promise?
