There is some confusion as to the attributes and character of Enyo. The poet Hesiod insists that she is rather lovely and fair-cheeked ... in his poem, Theogony, Enyo is said to be robed in saffron and her sister, Pemphredo, is clad in beauty. The two sisters were gray from birth and, according to Hesiod, not ugly or hostile. They are the daughters of Keto (Ceto) and Phorkys (Phorcys) and sisters of the Gorgons and the Hesperides ... mortals and Immortals refer to Enyo and Pemphredo as the Graiai, i.e. the Gray Sisters. (Theogony, lines 270+)
However, when we encounter Enyo in The Iliad, she is leading the Trojans into battle with Ares (god of War) ... her fierce war-craft is compared to that of the Grim Goddess, Athene (Athena). (Iliad, book 5, lines 333 and 592)
When Perseus was seeking the head of the Gorgon, Medusa, he consulted the Graiai and found them to be hideous ... they had only one tooth and one eye between them. Perseus presumably took their eye and tooth as ransom until they reluctantly revealed the location of the nymphs who could supply him with the Cap of Hades (which would make him invisible), a pair of winged sandals (for flying) and a kibisis (a bag to carry Medusa’s severed head) so he could complete his quest for the head of Medusa.
Later descriptions of the Graiai included another sister named Deino.
The line numbers listed here correspond fairly well with the Lattimore and Murray/Wyatt translations of The Iliad. Other translations (Fitzgerald, Fagles et al) do not correspond as well but, with a small amount of effort, you should be able to find the reference you need regardless of the translation you use.
