What language are the Marauders speaking?
(Each individual word is sent into a different language in google translate. Floating your cursor over the text should display the translation.)
(Well, everyone else was isolated for the same amount of time, but can understand each other just fine. )
(I was chalking that up to there being inter-bunker communications, as otherwise, with the length of time people have been apart due to the radiation, languages would have diverged to the point that they would be difficult to understand, if at all.)
Before I shoot everybody for language barriers, everbody speaks the same language
The deep metals in the desert isn't ok
The bombs are not ok either
(You used the word 'Millenia', which implies several thousand years. From the sources I've found, that length of time would cause the languages to change to a point where they wouldn't be understandable.
With the tools available, I would estimate deep would probably be around 100-150 meters down.
Rather than bombs, what about unstable crystals? Don't lie, you've confirmed the setting, and I know that in that, there are crystals that reproduce magic abilities. Heck, the hammer is made out of one!)
Also, there was already one city state in the East Desert called Maramia.
(If that is true, I'll pull out, I'm causing too much contention.)
