Nice deatils there Queen. But I should correct you about one thing. Bidur later became the prime minister of Dhritarastra. He was Dhritarastra's eyes in a sense, but not the one to narrate him whatever happened in Kuruchetra. Sanjay, Dhritarastra's old time "sarathi", was the one to narrate the war. He was given the "Dibyadristi" by guru Vyas.
