On sacred swores

There are multiple versions of the Troyan War. Multiple interpretations of Illiad. The most accurate tells that Greeks arrived and conquered the coast around Troy, but were incapable of pass the walls (of course, since those walls were being built by Apollo and Posidon, centuries ago). As a result of this tie, the war enlarged it for 10 years.

During this combats, Achilles and his men took over an Apollo's sanctuary, and got lots of money, jewels, and golden or silver objects... And also the priestesses. One of this was Brissedis, niece of Priamus, and was the cause of and argument between Achilles, who claimed be the only person that enjoyed the virgin, and Agamenmon, who claim the right to possess Brissedis since he was the King of Kings and The Comander in Chief of the Armie.

As a result of the fight, Achilles showed his famous anger, and retired his men from the battlefield. A terrible lost for Greek armie, whose men started to loose ground, and Troyan armie, led by Hector, the favorite son and heir of Priamus, started to gain ground.

Finally one day, Achilles men appeared in the battlefield, and the battle between Achilles and Hector began. But this time, Achilles seemed to be slow, unable to manage the sword as usually, and Hector ended him easily... Just the men on the ground was not Achilles, but Patroclo, his lover. The sadness extended among the Greeks, and Troyan armie didn't take that as a victory, for you don't celebrate the death of kids, and Patroclo was so young...

Achilles, infuriated and with no comfort at all, went to the very walls of Troy, and called for Hector. The Troyan Prince appeared, and tried to make a deal with Achilles. "whosoever of us die, may the other give his body to his people". But the Greek champion refused "there is no deal among lions and shepherds. Now let's fight".

Achilles killed Hector, and fastening his body to his chariot, (as well as Alexander many centuries later) he went back to the Greek headquarters, and did not permit to buried the body at any circumstance.

Tow dais later, during the night, Priamus, desguised as a beggar, appeared into Achilles tepee, and claim the right to give a correct funeral to his late son. He convinced Achilles, telling him this was a sacred oath. All men must rest among their forefathers, all men must pay the price for Caronte. All men must rest in peace. Achilles  asked for the pardon of the king, and made a deal with him. Twelve days of truce between Greeks and Troyan. After that, he returned to the Greek ranks, and finally was killed after Paris shooted an arrow towards his heel, the only part of his body vulnerable to an attack, since his mother grabbed him by the heel when she bathed him in Sticks loch.

So now Greeks and Troyan had lost their champion, they were exhausted, and the war seemed to be eternal...
