The name "Eldar" comes from J.R.R. Tolkien's elves, who in their own language were called "the Eldar". The history of the Eldar in Warhammer 40,000 mimics that of Tolkien's elves, to the point that they are a "dwindling race" in the game universe, as the elves were in Middle-earth's Third Age. Incidentally, GW has actually copyrighted the term "Eldar".

The Lizardmen are a faction in the fictional Warhammer Fantasy setting, and an army in the tabletop wargame Warhammer Fantasy Battle (based in the same setting), which is created by Games Workshop. The Lizardmen forces have a mesoamerican / Aztec themed culture, and are composed of various reptilian and amphibian creatures, including many based on dinosaurs and pterosaurs.
