That book series, Legends of the Dragonrealm, contains probably about 15 titles now and I am now reading the 6th book. It has arrogant, savage dragons, huge armadillo-like creatures, aggressive and savage bird-people who communicate by sending jumbles of images/feelings/sensations/thoughts to each others' minds and use medallions filled with magic to fight, but even without medallion they are powerful sorcerers, they are also very cunning and deceptive, and even have powerful muscles, talons and beaks to tear into probably anything but dragon skin. They are also fast... Scary, huh? :P The dragons can shapeshift into human forms, where they seem to wear armor but it's actually their skin, the dragonhelm is part of the face, they occasionally let a few hisses slip when talking, their faces are obscured by the dragonhelm, because they don't actually have much of a face (I don't understand their faces), their eyes are glowing orbs, in human or dragon form. And that transformation process is described in amazing ways, when I think of the transformations, the memory is almost as vivid as if I had seen a video of it. There are beings that are of the human race, but not much like humans at all. You have the wolf-raiders, who are wolf-men with powerful sorcerous abilities. The Vraad, the near immortal beings who change their faces, hair, stop aging, illness, conjure up food, teleport, build gigantic citadels that can shape itself according to their masters' desires, ofcourse they have insane offensive and defensive spells, all of that through their god-like sorcerous abilities... Imagine me becoming one of them o.0 And there is so much more to this world, so much things to do in a lucid dream by taking ideas from this book. There are countless other races, I haven't been introduced to them.. Yet :D And every race has its own powers, personality, type of civilization, history, most of the major races almost as deadly and fascinating as any other. All of this is vividly stored in my head, I think you'd agree that if I was a skilled lucid dreamer, I could have so much adventure... So much fucking adventure! Also, beside the major races there are also minor drakes, wyvers, those creatures that look you in the eye and turn you to into stone, and all drakes are slightly different, depending on where they live, were born and they also differ from drake to drake.
