Once you get your space ship and beat the three planets (lava, ice, forest) you go to the astrod belt at the bottom right of space and fly around in it until you find the crystal castel astrod. Once you land on it you go up to the other knights and pull the sword out of the stone (you can get the sword out just by tlicking on it) and go through the portel once it opens up, go through it. Then go down to the main entracne of the castle. Go to the princess and talk to her, but once you give her the three magis items she's going to turn into Mordred. Then he runs inside the castle and you have to solve the muzzle to go inside and see him again.
