Going to clear things up:Adunians are not half elves, we are from a tribe of humans and a tribe of elves who become one, their children were half elves and then evolved from there. Adunians=Not Half elves
The level of genetic variation required for this does not happen in years.
Also, if your not half-elf, there's no way you can call yourselves pure human or pure elf by any means so pseudo human I guess would be the best definition.
