Okay this is one scatershot discussion. But I noticed one thing, people mention humans getting together to take down threats, this DOES happen, oh not every human, but they do organize in the face of a threat. Now compared to the MUCH MORE INDEPENDENT AND FICKLE mind of a fairy true organization should kinda become almost impossible beyond small bands. You think human personality's clash, take supper predator entities who are already geared to think of other intelligent entities as food, with less of a social drive, and have on average a 14 year olds attention span/attitude (and I am being giving here)and see what happens.
