First of all, Enworld is a flat world that rides atop a single great elephant named Morrus. The world is similar to Pratchett's Discworld, but we have a single androgynous imortal elephant to ride across the universe.
Discworld
At the center of the globe there is a single great city named Orussus Trade City. Orussus is the home of thousands of classic adventurers, and is alongside a body of water, and surrounded by mountains with roads leading in most directions.
(I need some notes on the other cities, if someone could confirm the "how far north and south of orussus" that would help").
Other major landmarks include 6 great towers that represent the elements of Earth, Fire, Wind, Water, Positive Energy, and Negative energy. Each of the primary elements is surrounded by representative countryside. The towers go down into the root of Enworld's disc. They are near the edges of the world, equidistant from the center.
Originally thread on the towers arcane...
Fire - This elemental region is covered with volcanic activity and dangerous natural phenomenon. It never rains within a hundred miles of this tower, so it is surrounded by desert beyond the mountains. (Volcanic mountains around the tower, surrounded by deserts. Located in the Southeast.)
Earth - This is the most temperate tower, having been one of the most fertile growing lands in history. Metal veins run deep around this tower, and wealth is common. The tower itself is surrounded by mountains of stone and metal, once bastiosn to passing civilizations. The land is flat beyond the mountains, and forests populate this area. (Large mountains surround the tower, surrounded by forests and green plains. Very traditional DnD region. Located along the Northeastern corner of map.)
Wind - This region is the most isolated of all the towers. Where the earth, fire, and water towers are protected by natural phenomenon, the Wind tower is seperated by a lack of such. The land around the tower of wind has fallen off Enworphant's back, ages before any can recall. Now the tower, jutting down towards the planet, is surrounded by nothing but the uncontrollable winds that it controls. (Broken off section of map, tower sits on the edge surrounded by tempests of wind. Located along southwestern corner of map.)
Water - The tower of water is part of the largest ocean of Enworld. Here you have a tower surrounded by mountains of ice and then by water for miles. Near the tower itself, it is nearly impossible to land a boat. Isolated and cold, even during the summer, the water tower is an isolated place. (Located opposite fire tower, far Northwestern tower on map.)
Positive Energy - This tower, like all the others is a large grey stone pillar. (really havn't figured this one out, thinking mount celestia type thing, farthest north).
Negative Energy - A lone grey tower, surrounded by the graveyards of the dead. It is rumored that all evil bodies and souls migrate to this place after death... a place made of bone, surrounded by the unfertile soil of death. (Located farthest south).
