Things to be mindful of during Character Creation:
Aspiring Summoners and Conjurers beware: many conjuration spells simply do not function.Current theory is that there used to be connections to other planes, but they are now weakened,hidden or destroyed.
Religion does have a place in Aithea, but most of it is not directed to a specific god. Many people practice a form of ancestor worship or nature worship. The elven order of the moon worship a goddess of the moon. This means that clerics mostly just worship ideals, not gods.
Wizards are very rare, and have no place of study to turn to for training. Most sources of arcane power come from sorcerers. A result of this is that scrolls are also very rare. Magic items used to be rare but are becoming more and more common. High level magic items are still rare or nonexistent, however.
Guns are allowed, but still quite rare. Stroln has most of the worlds firearms. The firearms are only of the "early" category.
