Doppleganger: Grouping: magical humanoid or spirit. A monster or spirit which appears to look and act just like its victim in many ways, but is subtlely different and has a motive to scare, kill, demoralize, or just confuse. It is just as strong and has the same skills as its victim, but it never gets tired. Usually sent by a wizard, a demon, or a god. The word can also be used to describe a person who looks almost exactly the same as someone else but is not a biological twin. Genre-shapechanger. Source: Here and there, I don't remember specifically. In nethack it is another type of shapechanger which takes the form of character classes the player can be. There is also one in Zork III (the text adventure), although Zork doesn't use the word "doppleganger". The nethack description of "Aleax" is like a dopperganger, I don't know if "Aleax" is another name for it or if it is something else that is similar. I'd like a more origonal source for this.

      Dragon: Grouping: magical beast. Shape: winged lizard. Different ideas of a dragon very in size anywhere between 12 and 50 feet from head to tail, sometimes even longer. They are famous for living in large caves in mountains, guarding large treasures, and destroying towns and countrysides with its firey breath. A knight is often not considered a hero or worthy adventurer until he has killed a dragon, rescued a woman in danger (sometimes by killing a dragon), or completed another type of significantly great quest or battle.
That, at least, is probably the most popular view of a dragon in our culture. There are many different views of dragons. Some dragons are intelligent and can cast spells and have telepathic powers or magic in their voices, others use very little or no magic and act more like wild beasts. Some are inherently evil, and some, especially in eastern culture, are benevolent and good. Often in computer games, different colors indicate different types of elemental dragons. Genre-reptile. Source: various ideas..

      Droan: Grouping: magical humanoid. A Droan's skin is very tough and usually coal-black in color. Made by magic from a sea vestrage, it has webbed hands and feet and is very muscular. It is the servant of whoever made it. In Garefen: They live in the sea around the island of Rixsah. They were made by an ancient samon. When that samon was defeated they hibernated until there was another samon on Rixsah to serve. Genre-lethkel/magic invention. Source: mine, appears in "The Redemption of Wesley Kracken."see also samon.

      Dwarf: [1] Grouping: nonmagic humanoid. av.height 4'4"-5'2". In appearance, they are small but stocky and strong and almost always have beards (even the women). Dwarves live in large cave cities in mountains and are great miners and metalworkers. Their lifespan is about 250 years. They are proud and highly value honor in war and all their doings, but their greed has been the cause of much strife. Genre-earth. Source: my slant on popular idea and Tolkien.

      Dwarf: [2] Grouping: fairy. These dwarves are somewhat alike in appearance with mortal dwarves, but are uglier or rather more funny-looking and often have deformities in their feet. Their personality is mysterious and mischivious more similar to other fairies than the non-fairy dwarves. They will not come above ground without disguising as an animal such as a frog or turning themselves invisible. One large similarity between the two types of dwaves is that both are master miners and blacksmiths. Genre-earth fairy. Source: nethack description, other popular idea, fairy stories.

      Dynthe: Grouping: fairy. Shape: humanoid, av.height 3'2"-4'. Like several types of fairies, these appear like children except Dynthe like to walk on air so they don't have to look up to taller people. Also known as "Dream Fairies," Dynthe have powerful magic in the area of illusions, sleep, and of course dreams. Genre-gnome-related fairy. Source: mine, doesn't appear in any of my stories yet.

      Effretti: Grouping: magical humanoid. av.height 8'-12'. A giant who seems to be made of fire. Sometimes called an "ifrit", the term "ifrit" can also refer to smaller versions of it. Genre-ifrit. Source: The Pit, has appeared in other games I have played, would appreciate a more origonal source.

      Eirrinel: Grouping: fairy. Shape: batlike, same size or slightly larger than a bat. This species of Xafeni fairy lives in the Silver Land to help rescue people from the grepse. Like other Xafeni, they have magic which is especially useful for working against the grepse, including the ability to let those lost in the Silver Land communicate with those outside. Their only weakness is that those they are trying to help don't usually recognise them as something helpful. Genre-xafeni. Source: mine, appears in "A Step Up."

      Elf: [2] Grouping: magical humanoid. Describing Quote: "The eldest and noblest of the speaking races of Middle Earth.. about six feet tall and somewhat slender; they were graceful but strong, and resistant to the extremes of nature. Their senses of hearing and sight were much keener than those of Men. Elves did not die naturally but could be killed.. Elves did not sleep but rested their minds by thinking of past ages or looking back at beautiful things. They [or at least some of them] could talk directly from mind to mind without words.. Elves and dwarves were not very friendly [with each other]." from A Guide to Middle Earth by Robert Foster. Source: Tolkien. BTW, that "Guide To Middle Earth" is a good reference for all things Tolkien, the author obviously did his research.

      Erlking: Grouping: fairy/demon. The word means "Elf-king," but they are far different from any other elves I've heard about. From german folklore, this evil fairy will appear harmless and lure people, often children, to their deaths in the forest. In the short opera with the name "Erlking," a man rides through the forest with his son riding behind him on the horse. The erlking calls to the man's son, and the father can't hear or see the erlking. ("Oh, come thou dear infant! Oh, come thou with me!/ Full many a game I will play there with thee") The boy keeps telling his father that there is something strange calling to him, but the father doesn't believe him. And when the father rides out of the forest, his son is dead. Genre-sedhe. Source: German folklore and mainly from the "Erlking" opera with lyrics by Johann Wolfgang Goethe.

      Ettin: Grouping: non-magic humanoid. Ettins are two-headed, barbaric giants. Genre-giant. Source: Nethack, also in some other games, don't know where they're from origonally.

      Floating Eye: Grouping: non-flesh based. Shape-sphere. It is what the name implies, paralyzing with its gaze. Possibly the attempt of a novice wizard to imitate the Beholder. Genre-eye. Source: Nethack and other computer games, not sure why I included it here, but now that it's here why take it out?
