Everyone is born with eight skill slots, and the rarest skills devour most of them. A boy enslaved in a skill-orb mine has none at all, until a cave-in kills the noble who owns him and dissolves every slave contract, setting off a riot for the stored orbs. Too slow to grab anything worthwhile, he is left with a ten-slot orb that no human can absorb, except that as a reincarnator he carries sixteen slots. Now holding the world-altering skill Omniscience, he has to escape a surrounded mine and decide what to do with a power no one else can wield.
