I got some ideas about the land if you care to read.
Air - was thinking about that place in china that has those steep pillar like mountains that plateau off and every thing under them is drowned in fog, that but in the crazy extreme; mazy cliff sides boarder the gray haze of the sky over head before the hard climb up along the cliff face breaching out of the cloud line to be sucked into a clear sky and flat tops of the plateaus looking like islands floating in an ocean of whispy clouds.
water- Should be the mouth of a river, a large river that cuts across the land and or has many rivers feed into from the south. south west where the mountains are, the river would shatter the land into swampy low land with small blush of land there and here before feeding out into the ocean pushing into a speckle of islands. if its really a land of water would be the place a rain forest would grow and have a thick jungle maybe with a mess of bogs and still water making so you have to travel along large roots and craftwork roads if not just small boats.
more so the low, flat land that could support swamps, bogs and the such means the creatures (merfolk and such) could swim inland to whatever end and have a city others could go to. lols like venice but in reverse haha
Earth- strongly feel rivers should be made here and cut into the land of water would also feed into the idea that earth is super rich as farm land, more so being broader by volcanos. The mountains to the south would be have dense forest as the north would have jungle and that space between the two mountain ranges you could make into a low land and or valley and they would be crazy good farm land. As to the land itself when I thought about the land of earth i thought about Red wood forest with super big trees enjoying the rich land, Something like that where the plant life rather than being dense and tightly packed is instead massive and robust.
Fire- Black sand, gray ash deserts, jagged wings of obsidian and warped swirls of lava flow cooled between it all. Wind would blow from the ocean so ash and fall out would be swept to the northish. Could branch of that spin of mountains and feed it into the ocean making some volcanic islands. Mixed with the bizarre life adapting to the flow of lava and ash, earth quakes and desolation-- maybe like a stony bark tree that can safely smolder with fire but doesn't catch flame pushing high into the sky to safely grow and rather take root into the ground expands those roots to snake and coil around stones and hard places to set it.
ice- just a tundra, snow and ice breaking on the face of mountains lol not too much to say, could instead have it be more of a complex net work of tunnels and mine shafts with maybe some ruins along the mountains temping the bold to explore them.
Energy? - by the name I take its just rich in raw energy/ magic? mixed with being in the middle of every thing so it gets a bit of each. hmmm i feel like a single monolithic wave of earth of a mountain where the town is thats super rich in magnetized metals that attract thunder storms and such is the site of a near endless storm system that is fueled by the volcanic winds from its south west as well as feed heavy rain into the land of water and supporting MoRe jungle. The major mountain would then have rolling hills pushing away from it that could become pools springs--mean sit in a hot spring, drink and watch an endless thunder storm, id pay money for that. ohoh
Just my thoughts! hope some of them are useful for that think tank.
