Remember, 3e is all about crunch, not fluff. Manual of the Planes was about as fluffy as it got. Now, 3.5, on the other hand, shows some promise for more fluffyness. The Draconomicon, for example, looks to be about 75% fluff (dragon tactics, society, etc.)
Arc, no one cares about the voulge. It's all about the all-pike.
