There, Duncan barely managed to escape! Then he ran away from Andrias! And soon after, Andrias retreated to a castle and stayed there! I gathered a decent army (1.1k militia, 700 archers, 560 paladins, 100 griffins, 70 inquisitors, 50 paladins, and 23 archangels) and attacked Andrias and his castle. Then I took over the castle, boarded a ship, and encountered some weakling with 15 fallen, 30 Izabel knights, 60 adepts, etc. I easily defeated him and completed the game! :) :) :)
