The goblinesh more or less served in near-slavery under both the Empire and Shaya'Nor in the ancient days, used as marauders and occasional hordes. During the aftermath of one of the many cataclysmic wars, many of them managed to just drift off and make their own way, literally "filling the cracks" between nations and regions.
 
There is certainly a "strong lead the weak" mentality in most gathers, especially in the north, but mental, intellectual, and spiritual strength are becoming more and more valuable commodities, especially in the south.
 
Think Klingons trying to establish themselves, slowly, as more than warriors in the greater society. Some are highly progressive, some are violently dedicated to the old ways, while most aren't sure what's best for them either way.
 
One more thing - many (though not all) of the northern Gathers have a high number of their populations as worshippers of Ceynara (as a goddess of strength, warfare, and related concepts). Some few actually also recognize Vainar as the God of Secrets and Knowledge, and see the rest of the Ascended as weaker gods, cast out from greater divinity.
 
Hope that helps some.
