The World of Avlis

I was wondering about a couple of things about Avlis and how it appears from the characters' perspectives.
Does it have one moon? Does it look like Earth's?
One sun?
What's the set-up of the planes - the standard cosmology of the great wheel plus inner planes? And how much would our characters be expected to know? For example, would a bard or wizard be pretty knowledgable, or is it something that is talked about as pure theory by everyone except the most powerful characters who can actually walk the planes?
Also, regarding the history of the gods, Fairy War, the Great War, etc., again, what should we allow our characters to know, especially "educated" characters such as wizards and bards?
Many thanks!

Standard planar cosmology with great wheel, yes.

One earth-like sun. One moon.


Clerics will know more about religion and philosophy and history. Wizards and sorcerers will know more about the planes and general magic theory. Bards will know most of the stuff posted in the information forum... just pick what your character would be most likely to know.

The average commoner lives under semi-feudal conditions with an apprentice system of learning in most cases. Some go to academies of magic or clerical learning institutions, but not many. You can assume that your adventurer has had some education, unless you are a barbarian or you don't want your character to be educated.

A generally educated person will know the basic creation theory, and the existance of the races, and who most of the gods are. They will also know that magic exists but that's about it, unless they've seen it.

thanks!
