Keeping any Aiakides alive? Never! The same would be for Seleucids and Ptolemaioi (as soon as the King catches the "Alexander Fever").

Interesseting developement last night: Nikaia rebelled from the Seleucids to me, spawning several units of Galatians. As soon as the King entered Bythinia a Hellen character was offered for mariage to his eldest daughter who then appeared in Nikaia even though it was besieged. I think this plot demands a lot of roleplaying - or even an AAR.
