Erebus :
In Greek mythology, Erebus /ˈɛrəbəs/ (Greek: Ἔρεβος, deep darkness, shadow), representing the personification of darkness; for instance, Hesiod's Theogony identifies him as one of the first five beings in existence, born of Chaos. Erebusb fathered several other deities with Nyx; depending on the source of the mythology, this union includes Aether, Hemera, the Hesperides, Hypnos, the Moirai, Geras, Styx, Charon, and Thanatos. Erebus is also used of a region of the Greek underworld where the dead pass immediately after dying, and is sometimes used interchangeably with Tartarus.

Hesperides :
The Hesperides /hɛˈspɛrɪdiːz/ (Greek: Ἑσπερίδες) are nymphs who tend a blissful garden in a far western corner of the world, located near Libya or the Atlas mountains in North Africa at the edge of the encircling Oceanus, the world-ocean. The nymphs are said to be the daughters of Hesperus.

Palinurus :
In Roman mythology, especially Virgil's Aeneid, is the helmsman of Aeneas's ship. Later authors used him as a general type of navigator or guide.

Nephele :
Nephele (/ˈnɛfəˌli/; Greek: Νεφέλη, from νέφος nephos, cloud; Latinized to Nubes) was a cloud nymph who figured prominently in the story of Phrixus and Helle.

Sterquilinus :
In Roman mythology, Sterquilinus (manure; also Stercutus or Sterculius) was a god of fertilization. He may have been equivalent to Picumnus.
