I decided to go with milestone leveling. I leveled the PCs to 2nd after defeating the boar and to 3rd after rescuing the Oracle.
They are now in Estoria attempting to save King Pythor's daughter. They wanted to know how long until the full moon, so I randomly rolled a d20 + a d10 and got 7 days. They considered following leads and doing one of the labors during that time but ultimately chose to stay in the city.
The situation has gotten a bit messy.
They listened to Kyrah when she said challenging the centaurs would be suicide, so they tried the negotiation route. The aasimar who looks like a medusa went to Gaius under the pretense that she was selling out / betraying her fellows. He agreed to swap out Anora for all the PCs minus the aasimar, but she balked and said she didn't think the others would agree. She had boasted to him that she was a master of sleep magics, so Gaius was confident she'd be able to figure it out. She then tried to hit him up for 500 gp for the "rare magical reagents" she'd need to be able to put them all to sleep but he wasn't buying any of that.
In the meantime, they had already stashed some weapons near Estor's Rock in case they went ahead with that plan, but since the aasimar's player didn't think it was going to work, they had the rogue observe a cow sacrifice. He saw that two basilisks came out of the river, and he then tracked them north to their lair.
It is now the day of the sacrifice. The PCs did not agree to be sacrificed instead of Anora, so she is still going to be chained to the rock. The PCs, meanwhile, are lurking in the entrance to the basilisks' cave, waiting for them to come out of the submerged part so they can ambush them with shiny bronze shields. (They didn't want to do this any earlier in the week in case Gaius and co got suspicious.)
The problem I have is that the basilisk lair is 1 mile upstream in rocky terrain, and the book states that killing the basilisks won't save Anora since Lutheria sends harpies to ensure she dies. However, I didn't think Lutheria would send harpies for a cow, so the PCs / players don't know about them, which means that if they wait in the cave for the basilisks, they probably won't make it back to Estor's Rock in time to save Anora from the harpies -- which might come across as me punishing them for getting creative. (Although it could also just make them hate Lutheria that much more.)
My one thought so far is to have Kyrah warn them that the Titans aren't going to play fair and that killing the basilisks may not be enough to save Anora. I'm considering also having her say that she doesn't think lurking in a damp, dark cave is particularly heroic and that she thinks they should take the fight to the basilisks in their lair.

On a completely different note, I also ran the graverobber scene in the agora, thinking it was a good way to show the players that the laws of Thylea are a real thing. After listening to the merchant explain why the thief was starving to death, the warforged artificer offered to buy the necklace, thinking that he wouldn't be affected by the curse since he doesn't need to eat.
On the one hand, that was quite a clever thing to do. On the other hand, I don't think the cosmic forces of Thylea will appreciate his attempt to cheat. I am thinking of having him start to suffer exhaustion levels anyway, especially since he is not an outsider. He was once a living Thylean native whose soul was infused by a jancan smith into the construct body (the player chose Gifted One as his epic path, so I took a page from the lore behind Dragon Age golems). So he should still be subject to the curses and stuff in some way. Plus, all the other players were like, "Dude, the curse is just going to change and you're gonna be screwed. Don't do it!" And he chose to do it anyway.
