“It’s all in a day’s work for this good knight!”
Clad in shining armor and with his sword and shield always at his side, the Heroic Knight is the greatest hero of his age. He rides across the land, fighting for justice and righting wrongs wherever he finds them, and asks for nothing in return except the happiness of those he has helped.
With so many good deeds to perform, even a Heroic Knight can get confused sometimes. He means well, but occasionally he does try to rescue dragons from princesses. Fortunately, the dragons are usually grateful enough to give the kingdom back its stolen treasure!
