Official Proposal: World formed from Fire to Ice, and goes from one to the other across it; extreme heat, fire, and molten rock on one end, extreme cold, ice, and frozen air on the other. In the middle, where they meet, rock is cooled and solidified to earth, while ice is melted and becomes ocean. The sun, if any, provides light but little warmth; most warmth is dependent on location. Each of these three realms occupies around the same amount of space; fire, ice, and temperate/oceanic. Around 20-30% of the temperate area is covered with 'islands' at any given time; these islands stretch seemingly endless down into the deeps (another 40% or so of the ocean is 'covered' with subaquatic landmasses that provide a bottom to the ocean; the rest seems to be bottomless, just as the ice sheets and scorching fires/roiling lava of their respective realms seem to go down forever; many of these subaquatic landmasses are attached to or portions of landmasses that do rise above the waves), and drift slowly, sometimes smashing into each other. These can cause the islands to become attached to one another, formed a larger island, smash apart one or both, or simply bounce (with a great deal more violence than that implies) off of one another. These islands can be very, very large, sometimes even continent, though larger islands will often eventually be subject to stresses that cause them to break apart. Because shards of their respective realms can be carried with them when land forms/breaks off into the ocean, there are both volcanoes of fire and of ice; when these collide, a tremendous battle is had by their respective forces, usually but not always ensuing in their mutual, though glorious, defeat. The weather patterns caused by perpetual lands like this should be pretty interesting, though not necessarily static. Bounded on one end by cold so intense that it does in fact reach the equivalent of absolute zero, and what amounts to the core of the sun on the other.
