The Free Worlds League Parliament passed a law that specifically barred the offspring of this union from becoming Captain-General, though it did not exclude Christopher himself. The Parliament considered Sian a hostile neighbor and did not want to take chances allowing the family into the line of succession. Christopher's descendants became known as the "Sian-Mariks".
