OK SO-SOSOSO-
you ready for more Crow the greek mythology professor? Apologies, this is just my fucking JAM-
So the titans were divine beings, perfect, all-powerful figures, that ruled over the earth before there were even humans to rule over. And at the time. The leader of the titans was Kronos, God of time. Now, Kronos was married to Rhea, who was a fertility goddess. So she started having kids. Obviously. This would be the first 6 gods of the pantheon, the oldest if you will. And the oldest, the first one to emerge? Hades.
