Star of the Dark Blue Earth

Question: Your Incan supplement says that the only being that could non-violently deal with Perses is Hecate, his daughter, but what about his wife Asteria? Could she do the same, or does the story of her becoming the island of Ortygia mean that she's no longer among the living?

That's up to interpretation, so go wild! Asteria is definitely "out of play" for the Dodekatheon for most of their run, having turned into Ortygia/Delos and done nothing further other than pissing Hera off by aiding Leto to have her children, but in Scion's setting there are several possibilities for what actually happened to her. Being a Titan, it's unlikely that she's actually dead, since that tends to cause terrible repercussions for the World and we know of no star- or prophecy-related disaster that would match up to her demise, but that doesn't mean she's necessarily just loose on the World right now.

It's possible that the story of Asteria's transformation is a metaphor for her being consigned to Tartarus; while she didn't fight in the Titanomachy and seems to have been an accepted inhabitant of Olympus after the Titans were defeated, her defiance of Zeus and refusal to be his lover might have motivated him to chuck her in jail with her parents anyway. Hyginus, in particular, spins the story so that after Asteria had turned herself into a quail to escape, it was Zeus in his fury who threw her into the ocean to become an island. Ovid adds that Zeus turned himself into his eagle form to do so, making it a bird of prey pursuing a hapless little avian. In this case, Asteria could very well be out and about after the sundering of Tartarus, and just as available to interact with anyone you like as any other previously-locked-up Titan.

On the other hand, perhaps she really is the island of Delos, which still exists in the Mediterranean as well as in ancient myth (John and I wanted to go there when we were in Greece, but unfortunately it turns out you can't see an entire country in ten days). While normally a Titan couldn't turn into a landmark like that without being removed from the World by concerned gods or causing massive continuing problems from her Fateful Aura, a purview Avatar (or several in concert) could have actually turned her to unliving rock, dormant enough to never wake again. In some versions of the story, she turned into a quail to escape Zeus and was then forced to turn into an island when, upon running into the ocean, Poseidon started chasing her instead; she might have fully given up in favor of not living with these assholes anymore (like Cavillaca, who you'll also find in the Inca supplement). A few fringe versions also claim that the island transformation was performed by Zeus, Poseidon or other gods as a punishment, and it's not hard to imagine it might be a result of Poseidon's The Shaper combined with Zeus' The Arbiter or something similar. That leaves you a lot of interesting possibilities for a game: is Asteria actually dead and gone for good, and if so, did this transformation get around the usual rule against destroying Titans, or is it perhaps delayed in some way, about to happen if the island of Delos itself is ever destroyed? Is she still alive but trapped in some Terra Incognita that is only accessible from the sacred island, perhaps unknown to all except those who put her there (or to everyone, because only she knows she retreated there)? Is she the island itself, actually a living thing that somehow doesn't cause the normal consequences of a Fateful Aura, perhaps through her own use of The Wyrd in her extremity or something that other Fate goddesses such as the Fates or her daughter Hecate are doing? Now that the Titans have escaped, can she interact with or help her old cronies in Tamoanchan, or is she cut off from everyone?

If you do decide that Asteria is alive and well and capable of talking to people, then she certainly might be able to attempt to approach Perses, who at least didn't murder her while they were married and could be assumed to be fond of her. The two haven't seen one another for millennia, of course, so it might be a rocky reunion, and Perses is likely to go even more bananas with Vengeance if he finds out about the Olympians' treatment of his wife after he was imprisoned, but it's possible she could calm him down enough to at least have a conversation. Unless he thinks she betrayed him by not helping in the Titanomachy, in which case all bets are off. Greek relationships are complicated and dangerous things.

It would also be interesting to see what Hecate and Asteria might do if reunited; Hecate works for the Dodekatheon, but she's still more Titan than god and always has been, and herself and her mother, both brimming with Fate powers and Vengeance, might make life very uncomfortable indeed for the gods who have mistreated them.
