Seeker of Thrones 5-36
“And Prince Kassardis was given three vessels of wine, and three wives, and three rings to gird his ring-fingers. But Kassardis’ heart was heavy at his wedding ceremony, and no amount of wine could float it up from the depths it had sank to. For this ceremony held with it deadly promise, for it was custom in that part that the prince, within a week of his wedding, should choose a favorite wife. This was a marker, a battle drum of sorts, between the three wives of the great house of Ium-Am. The battle only ended when one wife stood, scarred and bloody, and the remainder were dead or exiled.
Kassardis was sick of this slaughter, and the hollow wreck of a man he called his father. His three wives were very pretty, but they were cruel as hawks. Even as he stood there besides the marriage pool, he could see the bloodlust glow behind their veiled eyes. It was for that reason he took his naming dagger and traveling cloak and fled his tower one summer night.”
