Know why there are no male Adventuring Mithras? Because They all have a Harem of like 10-20 female Mithra slaves that do housework and anything else you command them do. Why go out into the world, risk your life, and deal with adversity when you all you have to do at home is issue commands, make more Mithra, and punish your disobedient slaves? All adventuring Mithra are basically escaped slaves.
