Lord Zack's Planescape
Elemental Plane of Fire
Everything is alight on the Plane of Fire. The ground is nothing more than great, ever-shifting plates of compressed flame. The air ripples with the heat of continual firestorm and the most common liquid is magma. The oceans are made of liquid flame, and the mountains ooze with molten lava. Fire survives here without needing fuel or air, but flammables brought onto the plane are consumed readily.
