I want to take the Lightning Elemental request so I have a question. This monster really exists?
Yeah. 2ed (more specifically, Planescape) had all of the demi- and quasi-elemental planes fully fleshed out, and pretty much all of that was lost in 3ed.
The Plane of Lightning is the quasi-positive plane between the Elemental Plane of Air and the Positive Energy Plane.
Here is some further reading (the author made a few changes in his explanation, but it's pretty good). (

Also, Osle, if you want, you can copy
this link into the "Bunch of Elementals" spoiler in the first post, as more of an explanation. (
This link goes into a bit more detail, but the author also made a few modifications to the original)
