Do you think Tywin was behind the events at Duskendale ? This is from stdaga on the Last Hearth forum .
I am sure there was hope for more people to join into supporting Darklyn's cause at some point, which seems to be about taxation and trade rights, but I am not sure it wasn't until Darklyn found himself trapped into a corner that he felt that way. Tywin was instrumental in refusing Lord Darklyn's request, so he might have been hoping that would anger Darklyn enough that he did something stupid. Which he did when he took Aerys hostage. Still, if Darklyn wanted Aerys dead or off the throne, he could have or would have killed him. Instead, he held him captive, which really could only end badly for the Darklyns. This also could have been an impulsive act on the part of Darklyn, one that he found himself stuck with. Time only made the situation worse. And Tywin did tell Aerys not to go to Duskendale, but did he do this is a manner that promoted that Aerys would want to go against Tywin's recommendation? The two men were pretty much on the outs by that point. Certainly there are layers to what happened and what was intended with Duskendale. But from what I read of the situation, I don't think it was intended to be a rebellion, at least on a national level, more of one family/area demanding personal rights.
The World of Ice and Fire - The Targaryen Kings: Aerys II
Those who knew the resolve of Tywin Lannister knew better. Instead, the Hand's heart grew harder, and he sent Duskendale's lord one final demand for surrender. Should he refuse again, Lord Tywin promised, he would take the town by storm and put every man, woman, and child within to the sword. (The tale, oft told, that Lord Tywin sent his bard to deliver the ultimatum, and commanded him to sing "The Rains of Castamere" for Lord Denys and the Lace Serpent is a colorful detail that is, alas, unsupported by the records).
Most of the small council were with the Hand outside Duskendale at this juncture, and several of them argued against Lord Tywin's plan on the grounds that such an attack would almost certainly goad Lord Darklyn into putting King Aerys to death. "He may or he may not," Tywin Lannister reportedly replied, "but if he does, we have a better king right here." Whereupon he raised a hand to indicate Prince Rhaegar.
Scholars have debated ever since as to Lord Tywin's intent. Did he believe Lord Darklyn would back down? Or was he, in truth, willing, and perhaps even eager, to see Aerys die so that Prince Rhaegar might take the Iron Throne?
