(From the Bizzare Life Forms Challenge)
Here, where lead is energized to the point where it behaves like carbon, it has taken elements from around itself to create a kind of strange, metallic RNA. The body of life here is composed of magnetic fields, directing and in turn directed by shifting lead-iron molecules, in a hellish parody of aquatic life. Like the oceans of earth, there is a food chain, ranging from the simplest creatures, free-floating bits that convert the thermal energy of the molten sea to magnetics, and a series of larger and more complex creatures that feed off the magnetics of lesser creatures.
Hmmmm... a very strange thing would be, if this were a part of a "normal", Earth-like world. It would be hard for someone to travel down there, but in a volcanic eruption, some magnetic creature may make the mistake in travelling upwards. Before it dies a painful death in our freezing wasteland (as they would see our world), it could make a strange encounter for anyone near.
Now wait, what about Elementals?!
They are some kind of spirits of the elements, right? What if not? What if they are simply another kind of life? If they leave their habitat, they should theoretically die. But if there is magic, it can look differently...
A Summon Elemental spell does in fact three things:
1. Calls an Elemental
2. Coerces it to cooperate (or forces)
3. Binds protective magics around it, making it last long enough to serve
The very first Elementals must have been discovered through chance, perhaps by those with great powers of mind, that contacted these beings living deep down. After creating the necessary magical protections, the Elementals could discover our world. But even if not very smart, a bond could form, and the first Elementalist could call his pet for help. Knowledge has spread... and the spells were improved... and now can practically any powerful wizard call upon this help, enslaving the being in the process. No wonder that Elementals are considered hostile to everything.
I do not like planes very much, and I think some of you don't either. This idea can make Elementals a true part of the world.
