== Demons == 

 The section on demons is a bit off. It says they are the second dumbest of the fairy races after trolls. Well, while I won't dispute that they aren't exactly centaurs, what about goblins. Its explicitly stated in the books that goblins have brains the size of rat brains, have less than 10W of electric in the their brain and then there are dozens of more oblique references to their stupidity in the books (most notably commander root in the artctic incident - "Goblins, too stupid to live"). Even the goblin section of the article says that goblins have an incredible lack of intelligence. In comparison, the demons all appear to be pretty smart. They speak in full, complex sentances. Focused, brutal, bloodthirty, savage are all words I can see being applied to them, but stupid, not so much. They can read for one thing, build, have a fire brigade, use tools, none of which are hallmarks of stupidity.
