Nevermind, I mixed some things up somewhere. Cronus castrated uranus and chronos had no significant importance in the story (as far as I can tell)
gavvas:As far as i know gaia and uranus gave birth to the titans which later gave birth to the gods. the three most powerful gods, posiedon, hades and zues overthrew the titans and sealed them in different places. Chronos existed at the same time as Kronos as Chronos was the one who castrated him so they aren't the same diety
