Kyros was a to-be knight in Lastwall. HE never knew his father (an ambassador from Kyonin) and was raised by his mother and stepfather (both crusaders.)
When they died, he was trained by his godfather in the art of war, trying to balance his calm, rational elven mind with his human side. After multiple stints in the Fifth Crusade (Including the winning of 3 medals) he has looked more closely into the possibility of paladinhood int eh church of Abadar. Until then, he is content as he is.
