Items in [Parentheses] are part of the Secret History – events that happened but are not general knowledge. Some are known only to a very few researchers, historians and priests. Highlight to read, unless you are possibly going to play in this world. (The observant may notice some elements taken from the excellent scenario Hammers of the God by James Raggi. Don't read the Secret History if you intend to play this. Here's the Grognardia review.)
Comments are welcome and may well be incorporated.
Cosmology
There are four worlds with four stars and four moons that revolve in complicated fashion around the Sun, or perhaps the Sun revolves around them (no-one is quite sure and astrologers and other wise men argue about this incessantly). In one world, Kanosza, gods ruled – the gods of the celestial bodies and the Afterworld. In another, Jaruusz, a seemingly omnipotent principle, The Infinite, governed the mundane world and the Ether. On Ghildra, spirits roamed the world and the Guinee, the spirit’s home. On Ehlaar, the goodess Ehla and her children were the creators, ruling both Ehlaar and the Dreaming, until her children rose up and imprisoned Ehla in the Dreaming, which became the Nightmare World. [The Afterworld, the Ether, the Guinee and the Nightmare World all share characteristics, and otherworldly beings can seemingly operate through all these planes, even if they do not interact with each other.]
Kanosza is a world of continents, Jaruusz a water world with a giant archipelago, Ehlaar is a Pangaea, with just one continent, while Ghildra is a desert world with no seas, few lakes and many oases.
On each world existed a major species of humans and another intelligent species: on Kanosza, dwarfs, on Jaruusz elves, on Ghildra dragonmen and on Ehlaar trolls.
