Jobe is a neutral place yep...originally formed by a group of 12 uber high lvl Omni NTs who wanted more independence to do what they wanted (am guessing Izgimmer, Enfraam and co), but ended up more a place for NTs to go since well, everyone hates them so they went to hide in the ol' flying city.....Later on though FC being there normal selves changed it to be made by NTs and MPs (kinda fitting considering NTs cant do &$*% without a MP in tow even at lvl 200...anyhow this is sliding into a Nya style anti-MP rant :P but now it seems Jobes just the place where all the funky bits of kit comes from now, and where nanos etc are researched and made etc...oh and the other cranky experiments like the ones which open the trans dimensional window into the shadowlands.
As for protecting it, don't think it would really need much protecting since it like flys, and even omni don't mind it being independent (as long as it doesnt go clan) since they are blinking dangerous (trust me, nothing worse than a group of high lvl NTs together), from up there they could probably Kels Rome into a smouldering pile of ash in no time :P
