Just noticed this little tidbit in the Dragonborn section:
So, apparently WotC has decided not to bother trying to draw finicky distinctions between dragonborn and draconians, and just merged them. (The rest of the paragraph notes that draconians have "unique magical abilities" in place of breath weapons.) I wonder if half-dragons will end up getting folded in as well?In the Dragonlance setting, the followers of the evil goddess Takhisis learned a dark ritual that let them corrupt the eggs of metallic dragons, producing evil dragonborn called draconians.
