I am working on two mini-settings for Fantasy Hero. The first setting, which I am calling Viranduin is something I have been tinkering with the last year or two, but was forestalled by the unfortunate intrusion of mundane needs like rebuilding my career after a corporate buyout left me unemployed. Well that and, admittedly, a compulsive desire to play video games.
Viranduin is a pretty standard Medieval Fantasy setting. I wanted it to be a simplified, easy to get into setting to serve as a background for a couple of adventure scenarios I plan(ned?) on creating. My current status with that lies with a complete regional map and....not much else. I have been debating whether or not I wanted to use FATE or Hero before developing the rest of the setting. I've settled on Hero and will continue work when my mind gets back around to traditional European fantasy.
My other project literally started two or three days ago, though it is something that I have started and stopped many times over the years. I've always loved the Dark Sun setting for D&D and wanted to make an homage to that setting for a while. I even had a map at one point, but the map was not quite right. So that project sat idle until just lately when I had the idea of combining the concept of the Annunaki (Zacharia Sitchen's Ancient Aliens mythos) with Dark Sun.
Currently I have created the basic terrain map for the setting. Like Dark Sun, I wanted a metal-poor world. I always thought that Dark Sun would have been even more poignantly stark if it was once ruled by gods and then abandoned. I've also wanted to do a setting where the world was once ruled by beings that were effectively evil and now was free of that influence. This allowed for both scenarios at once. Being as their are no actual deities, there are no empowered priests. This is truly a low-fantasy world in every sense. Magic, though present almost everywhere, is minor. Swords are uncommon, being as all metal is preciously rare. Weapons are more akin to hunter-gatherer weapons (bows, spears, stone axes, etc.) and armor is usually boiled leather, bolstered by bits of bone or chitin. In other words, a world that only briefly experienced an iron age and then, only under the harsh whip of enslavement. If there are metal weapons, they are rare and legendary items.
I'll stop there and maybe create a Fantasy Hero thread to go any further.
