Welcome to Cerilia!
Have a look at this boards and you will find a free download of the 3. Edition Birthright Campaign Setting.
Birthright is a classic TSR-DnD-campaign world. It makes more sense to play it stand alone. However, in the Planescape “On Hallowed Ground” are some hints of including Cerilia in the mutiversum (apart from the fact that the multiversum idea has been canceled in 3. Edition).
well I cant find it all I find on the Dl page is not what im looking for.
Some other things I spoted with a little work could work for me.
Well now I found it. It seams that it will work better in PS then you think.
