Hesiod describes them as “wonderful children” and recounts how they earned their status and reputation.
Namely, when Zeus was preparing for the Titanomachy, he tried to assemble as many allies as possible, by promising whoever fights with him a divine office and appropriate rights. At the advice of her father Oceanus, Styx was the first one to join his forces, bringing with herself her four children. Zeus repaid her by declaring that, from then on, all gods will swear their oaths by her sacred waters and that Styx’ four children will live with him forevermore.
