Super spoilerific post for anyone who has not yet read Iron Queen. Fair warning…
A reader who just finished Iron Queen emailed the following. “This can’t be where Persephone’s story ends! The pantheon hinted that Zeus killing his parents might have been part of what drove Zeus crazy. Plus she’s a triple realm-ruler now, and she lost her mother, and Hades seemed to be a bit unhinged at the end. So what’s in store for her in the future? Are we ever going to see that?”
The sanity thing was just Athena speculating. Zeus was unhinged from birth. Something about his father attempting to kill him, his mother hiding him by tying him upside down to a tree for years, and spending his early years training him to kill his father. The whole slicing his dad open and rescuing his siblings thing only to find himself at once their savior and an outsider to their very tight inner circle, formed by years of being all they had in The Before was also fairly hard on his psyche.
As for the weight of ruling three realms, losing her mother? That gets explored quite a bit in the Aphrodite trilogy. Persephone’s adapting to her new role as queen of the Pantheon and her grief/trauma from everything that happens in Iron Queen. She gets a few POV chapters in Venus Rising to really emphasize that arc, but the Pantheon as a whole has to do a lot of adjusting throughout the trilogy. In the Persephone trilogy, the gods of the Pantheon were separate entities. They were used to working around each other, but they hadn’t truly worked with each other in centuries until the end of Iron Queen. Now they’re realizing they can’t just ignore each other until a big epic battle. That’s the very mentality that left them vulnerable to Zeus. There’s a lot of growing and adjusting that needs to happen.
As for Hades…this is lightly addressed in Aphrodite, and addressed more in depth here, but broad strokes, he’s not unhinged. He’s just mildly traumatized. He went through a lot in Iron Queen. Dealing with Zeus brought up a lot of horrible memories for pretty much everyone in the Pantheon. He also felt every second of Persephone’s torture, and he had to rip her arm off, and she’s waking up from nightmares where Zeus wore his face. That’s a lot to deal with even without the fact that he’s dealing with the fact that Zeus, Demeter, and Apollo are dead. They don’t think of each other as siblings, but that is millennia of history, good and bad. Then there’s the fact that he just kind of destroyed Zeus’s soul, and there’s some emotional baggage with that. And he also witnessed one of his worst fears (that his past will hurt the people he loves), come true for Poseidon.
It’s a lot. And I included that final scene to show that what happened with Zeus didn’t just happen to Persephone. She and Aphrodite weren’t his only victims, and they aren’t the only ones who need to come to terms with the events of Iron Queen. If Hades, the guy with millennia of experience getting over horrible things and a library full of self-help books, is rattled, you can bet every other god in the entire mythology is. And that will be explored quite a bit in the Aphrodite trilogy.
