EDIT: Actually, what I said before was rather stupid. I was going to put a story here (without bonus) anyway, so doing that.
Labarnas of Ugarit and the Great Plot
On the death of Katzuli, problems on the throne. Tabal had gone mad, and most of the court nobles (old but still alive) hated him anyway for his arrogance during the time he was sane. Contary to later myth, Mutawalli was a backer of the nobles in this conflict.
Tabal would end up escaping the court after a coup'de'tat, and Hattusili ascended the throne. Not wanting his own heirs to be weak, Hattusili would soon use a banquet celebrating his victory as a pretext to get the major nobility together and murder them.
Hattusili's government would have been stable, but Tabal had escaped to Cyprus, aided by his courtiers. Worse, he gave birth to a son- Labarnas. They were exiled for political reasons, but still had some sway over Ugarit politics.
Labarnas began creating a plan to retake the city- historically unique for how large it got away with being before finally being exposed. It managed to achieve this (though it was ultimately futile) through a complicated system of indirect messages through peasants in the countryside with writing, later switching to codes distributed around.
At it's height, the conspiracy had 200 people. Labarnas's own procrastination delayed action, however, as he wanted to ensure the loyalty of the city guards. This ultimately led to his downfall (though the coup would have by no means been a certain affair), as one of the conspirators finally leaked.
Hattusili was, though he wasn't going to die any time soon, on his death bed and believed to be dying. But others would ensure that Labarnas was outmanuvred- about double the number of actual conspirators were arrested as a side-effect, but Labarnas's plans failed.
Ultimately, his line fled into the countryside. For now, they would not play a part in the affairs of Ugarit...
