When I was making the "talent" selection for Corrin at the beginning, there was a selection for "Mage" but nothing for "Dark Mage", whereas the other talent names seemed to match with class names I've seen on the Wiki (e.g. Oni Savage, Apothecary, Fighter, Archer, etc.) I thought your talent eventually turns into your class - will a "Mage" talent turn into Dark Mage / Diviner class later?
Also, why are classes associated with certain sides? Is your eventual class selection limited by which side you choose? Why are starter classes from both sides available for the talent selection then?
Sorry for the questions - I'm used to playing FE games, but I've been getting confused with the two-version changes with Fates.
