Note that I haven't looked at the links yet, but I have read 2 of 3 of the forunner saga halo books . What I think I know ([u]PLEASE[/u] correct me if I'm wrong) is that the lord of admirals (LoA) is an ancient human that lead the humans in the battles in the human flood war and human forunner war. He was a mighty strategist human that lead fleets into combat against the flood, he mad a tough decision to attack a flood infected forunner location. The forunners took this as an attack and as an act of war, thus beginning the human forunner war. The forunner flood war soon begin and the didactic visits the LoA on his death bed speaking of his fear of the flood. The LoA later becomes a voice in the head of a human year after the forunner flood war (takes place after human forunner war), he human's name was either Chakas or Riser and lead them on their journey.
