Psyche - Psyche's only been with Eros, and now with Anteros. She's good friends with Melpomene, but that's about it. She rarely leaves the mountain, and only then to get chocolate. She gardens, paints and reads. She particularly proud of the Wisteria in her garden and mixes that smell with Vanilla to make her signature scent.
Styx - Styx has slept with Hades and Zeus on multiple occasions. She has a thing for power and believes she is better than most everyone else, immortal or mortal. Other than Zeus and Hades, she rarely sleeps with anyone. She's just not sexual. Styx smells like black pepper.
Selene - Selene has an open sexuality and isn't afraid of sleeping with someone she cares for. Her first lover was Helios, but they share more of a brother/sister connection than one of lovers. Hermes has hit on her on occasion, but she only laughs it off, she considers him just a flirt and doesn't take him seriously. Thanatos was a former lover and current friend. He shares a special part of her heart, and she'll always be crushing on him in some form. Endymion is still in her world, but she very rarely visits him, and just allows him to sleep. Zeus was also a lover. Friendship wise, she is close with Thanatos and, was close with Artemis, before she and Helios had their fallout. She still considers Artemis her friend and would be there for her should she need her. Selene smells like cold water and mint.
Ossa - I'm still developing her, but she's mainly a lesbian, only sexing men when it gets her something that she wants or when she's particularly intrigued. But that's rare. She shares a good relationship with Aphrodite and considers her a friend and an occasional lover.
Adikia - Kia will sleep with anything that shows interest. She's slept with Momos and Phobos for sure. Although I'm sure there are more gods in game she's at least hit on. She's not particularly complicated. She smells like men's cologne, whatever kind you like. That's what she smells like.
Hedy - Still in development. He's slept with Andy and Hori, I believe. I think that's it in game so far. He's a big baby when he doesn't get his way. When he's normal, he's not quite so babylike. Smooth. He smells like Cotton Candy and Roses.
Momos - Momos has slept with Ate and Kia. Kia only once, and Ate..well, that's ongoing. He's also slept with Deimos, and shares a mutual flirtation with the daimon. At least when Phobos isn't around. Momos has an aversion to being in pain. He has a tendency to be a bit of a chicken shit when pain is involved. Unless it's sexual pain, that's different, and only minor sexual pain. Severe? Doesn't play well. Momos smells like expensive cigar and woodsy cologne.
If anyone has any suggestions or additives to the back story that they'd like to include? Let me know. I'm always up for greater character development.
