Gideon's people were immune to disease, leading to an intolerable explosion in the planet's population. In order to reduce the population, Hodin had Odona meet with Captain James T. Kirk on a  of his starship, the . Using Kirk's blood, Odona contracted Vegan choriomeningitis, which Kirk had been cured of but whose organisms he still retained. The disease was a fatal one and Hodin's daughter's blood would be used to spread it among the inhabitants of Gideon to reduce the population.
