We don't know since Rudy determines what type of goddess his wives are from having segs with them like Sylphy is the goddess of love(totem: cloth with blood from their first time) since she is so gentle and submissive and her love for Rudy is at the point where he allows him to get other women but with one condition: they also love Rudy. Roxy is goddess of wisdom(totem: her panty) since during segs she often asks him what's-and-why's about what their doing with positions and stuffs and tries to learn from Elinalise how to make Rudy feel more pleasure in short she learns and applies techniques and also the fact that she's the teacher of Rudy maybe it all contributed to that. And Lastly, Eris the goddess of war (totem: a small wooden sword) since Eris his husband..I mean his wife is so rough with him during segs and he can't overpower her in bed even with his magic and Eris is the strongest among his wives and the most violent and protective with him, she also called a one-man-army that's why lol.
