Bagor Ironfist is a high ranking member of Clan Ironfist. He can usually be found in or near his wagon in the Orc Camp or checking on "guests" in the prison. His father is leader of the clan. He has an ongoing feud with Hadush due to his preference for mating with humans.
It is possible for Bagor to impregnate The Princess, assuming Vico has not already (if you haven't initiated the romance with him), as she begins feeling symptoms of pregnancy after a while of "spending time" with him.
The Princess may also make a few remarks about baring his children to him, though she doesn't seem to realise she is already pregnant, as she is confused as to why she is feeling so ill during that time. And unlike with the pregnancy questlog entry, Pia is not there to explain it to her this time.
