Orania Nasty Edition - Combining Era in a MAP

[Frostmourne27]

I though I'd revamp Orania Nasty Edition (find it on the Illwinter website under Dom2 files) for Dom3. Of course, someof it doesn't translate too well. I few questions for people: what age should I set it as? Originally, all eras were mixed (it was Dom2.) Ideally, I'd like to keep the original mix, but it has a few conflicts. e.g. Niefleheim and ashen Ermor. Suggestions on a workaround were all nations a are human playable? I do _not_ want to resort to a mod file.

Any other thoughts/requests would be nice too.
