Which underrated Greek deities do you wish more people knew about ?
While they obviously don't have many myths like the major Olympian gods, here's a few I think about not unoften:
Psamathe - A tragic Nereid who shares a more than few parallels with her well known sister Thetis.
Astraea - Most of her lore comes from Rome I think... but it's still pretty cool lore.
Zephyrus - Actually fairly well known, but he's only known as the villain in the Hyacinthus myth when there's way more to him than that.
Nerites - Prettyboy lover of Aphrodite OR Poseidon, I like to merge the 2 myths and consider him the lover of both though. Not that obscure anymore but I particularly like the myth where he & Poseidon have Anteros together.
Mnemosyne - Most underrated immortal lover of Zeus. Doesn't feature in many myths but her daughters are the muses who are all cool, and the story of how her daughters were conceived is a bit funny.
Delphin - Dolphin god. Poseidon's wingman who convinced Amphitrite to marry him.
Thalassa - Primordial Sea Goddess. I consider her Aphrodite's mother... and Delphin's... she's called the mother of fishes idk...
Perses & Asteria - Hekate's parents. I can't think of anything relevant Perses did except father Hekate but the way Hesiod describes his love for Asteria is described is so sweet. Asteria's story of being forced to give up her body to avoid being assaulted by Zeus & Poseidon is tragic, but her resilience is admirable.
The Horae (Dike, Eunomia, & Eirene) - Zeus & Themis's eldest set of triplets. There aren't really myths that feature them and are rather only mentioned in passing, but they're technically Zeus's firstborns out of his several hundreds of kids so I think they're kinda unique for that.
