A fairy is a tiny imaginary being with supernatural powers. Fairies are believed to be very beautiful and delicate. They help people when in a good mood, but they may harm evil people using their supernatural powers when they are angry. This land is ruled by the fairy queen who has a large magnificent palace. Fairyland is considered to be a land of lakes, lush green meadows, bright flowers, and fruit trees.
Children enjoy fairy-tales very much because of the enchantment and magical power such stories hold.
