The story begins here. The previous week begins here.
One day, Aegus, the king of Athens found a ship in his port that belonged to Presaron, king of Kadlandith. Being a Greek, and therefore a murderous pirate (I quote verbatim), King Aegus invited the captain and the valangzus of the ship to his palace where he poisoned them. With the valangzus safely out of the way, Aegus led a mob of soldiers down to the wharf to confront Androgiar, the principle officer of the ship, demanding that he surrender and promising that he and his crew would be safe. Androgiar, being the sort of coward who would rather give his life over to a man that has already proven himself a lying murderer than fight valiantly to a likely death, surrendered.
The Greek soldiers began tying Androgiar and the prisoners to the posts of the wharf as Aegus personally searched the ship. King Presaron of Kadlandith was the wealthiest of the Aghianar kings, and so Aegus expected treasures of immense value. At first he was disappointed because the ship seemed to contain only normal trade goods, but when Aegus heard the screams of the Aghianar captives, he went out to watch the executions and there discovered the real treasure.
Out on the wharf, a Greek soldier was walking down the line of bound captives and slitting their throats with a dagger. The dagger was not especially sharp and so each execution involved some amount of sawing and screaming. The rest of the Greek soldiers were enjoying the spectacle --laughing, taunting the doomed prisoners, and making wagers. In addition to the noise from the soldiers, many of the prisoners were screaming or weeping loudly or begging for mercy, but even in all that din, one shrieking voice stood out. Androgiar was screaming that he was the son of King Presaron.
