After The Fall: EarthFall
Only the Dorgal race has been somewhat accepted as a legitimate race within the AfterEarth world. Whether this is due to the close relationship that humans and dogs have shared for millennium is unknown.
A bastard race character rarely gets any positive traits from the interbreeding of species. Perhaps this is due to a genetic or dimensional difference between these races but that cause is currently heresy.
The only real change that occurs is that the bastard race character can choose to have elf features but take the human starting statistics.
