While Zeus was asleep with Hera, Hypnos went to the sea and told Poseidon he could now help the Danaans. So, as Hera went to Zeus to distract him with her beauty (with help of a charm from Aphrodite), Hypnos put the God to sleep. Hypnos had always loved Pasithea and agreed, forcing Hera to swear on the River Styx with all the Gods of the Underworld as witness. This time, however, Hera offered Hypnos Pasithea as a bride. Hypnos had done this once before for Hera, and Hypnos had barely escaped Zeus's wrath. This could only be done if Hypnos puts Zeus to sleep. His major involvement in The Iliad is helping Hera trick Zeus so she could help the Danaans win the Trojan War. Hypnos isn't the most involved in lore outside of The Iliad and an alternate version of Endymion. It wouldn't be the weirdest thing to happen in Greek lore. In case you're wondering, yes, Erebos and Erebus are thought to be the same. They had three sons named Morpheus, Phobetor, and Phantasos called Oneiroi, or "The Dreams." Hypnos and Pasithea live in the Underworld in Erebos. Hypnos married one of the Graces or Charities named Pasithea the personification of relaxation, meditation, hallucinations, and all other altered states of consciousness. Along with the “standard” things a God can do, Hypnos could also levitate or fly and has complete control over sleep. Even though he’s considered a minor deity and “lazy,” he’s actually very powerful. He’s a minor God and the son of Nyx, the Goddess of night, and Erebus, the God/personification of darkness, as well as the twin brother to Thanatos. Hypnos is the God of sleep and sometimes dreams. If you ever need a God that’s soothing and super chill, Hypnos is your guy.
