Note that LFR stopped being canon in year 2 or so.Again, you might be surprised. It depends if you count the large number of Living Forgotten Realms adventures released for public play during this time. But even if you don't, the number of novels published over the last few years is definitely not "a heck of a lot more" than the number of published supplements which take place in the Realms. 2012: 12 novels + ebooks, 8 supplements, 35 LFR adventures 2013: 5 novels, 6 supplements, 19 LFR adventures 2014: 3 novels, 5 supplements, 16 LFR adventures
Well, that actually already happened elsewhere much earlies. When Azoun was raising troops for his crusade against the Tuigans, Zhentil Keep sought a cheap way to contribute and send an army of orcs. Not only fought they bravely, their leader even received a medal from the hands of Azoun himself. The orcs then decide to settle in Thesk rather than go back to the Keep and lived a civilized and peaceful live with their human neighbours. That was a decade before the kingdom of Many ArrowsThe last straws for me when it came to the Realms was the 'getting along with orcs' in Drizzt novels
