Playing as Ajax (Salamis) in Mythos mode, upon conquering Zeleia I got an event that said a priest was said running to "Mount Ida" and that I should follow him there. The event also mentioned a prophecy related to the Palladium, and there's an achievement called "Broken Prophecy" that asks you to "Win a battle for Troy after successfully Stealing the Palladium."
But how do you steal said Palladium? There's no quest for it, no marker anywhere on the map. Neither Heroes nor Agents get a special "Search" action and spies can't even do anything against the city of Troy anyway. I've read a few people talking about moving your faction leader to the Troy region, but it didn't do anything in my case. (tried ending the turn in the region as well just to be sure)
Thanks for your help
