Basic run down, humanity has come in contact with and advanced being who calls itself the Enquirer. The Enquirer has selected a humanity to be its high class of society, above all other races in the universe, however humanity's arrogance made them go against the Enquirer leading, to all but a select few, the Enquirer to set back humanity's technology and knowledge back 500 years. For the select few, the Enquirer made them what the now 16th century humanity now revere as gods. However compared to the Enquirer they are weak, each only holding one particular aspect of his power: Gravity, Teleportation, Probability, Physical ability editing and Mental ability editing. 20 years after humanity's rebellion, all but 10 of the chosen have passed on from the unknown drawbacks of giving them the power. Changing the remaining humans biology and mental strength to accommodate these the Enquirer withdraw from Earth to find a more suitable race for his high class leaving the remaining 10 chosen humans as rulers of humanity.
TL;DR: Humanity comes into contact with a being who is almost a god, humanity tries to kill it, certain humans get powers and become rulers of the rest of the now 16th century steampunked humanity.
