Actually, Spring, I believe that troglos ARE as smart as humans. They are literate (see Castle Troglo's library), and, though some of them don't talk well, neither do some humans. Vothkaro spoke perfectly. You can't say that beings of small intelligence could cast spells well, or devise that machine in the basement. However, they come from an incredibly violent society. Most lessons wold be about combat, not fine culture. They direct their intelligence towards war. Also, they have managed to form bipartisan (military and religion) bickering. If you need to see a sentient race of inferior intelligence, just see the Hill Giants!
