Eberron is a D&D setting where magic has become mundane. Magic is so common place that there are magic mechanics aka magewrits. There is no clear line of good and evil the world is panted in shades of gray. The dead walk with the living animated by positive or negative energy. Air ships and Lighting rails connect the lands. Twelve Grate houses endowed with fantastic inherent powers controls the worlds economy. The world is touched in places by other planes of existence allowing power and energy to gather in curtain places naturally.
There is a lot more to the world I really wish to show others its places and people. It would be an RPG guild and would contain major cities and places.
