The Blue Dragon was evil, and the other dragons cast a spell on him and turned him into a small blue tree, but with the help of a Goblin he began to grow and so did his evil magic. The tree has large heart shaped leaves covered with fine poisonous stinging hairs. Any small creature that ventured close to the tree was sucked down and devoured by the roots that sprang out of the earth when they felt the vibration of movement above. The tree's blue roses had an intoxicating perfume and birds that alighted on the branches were soon overcome and fell unconscious to the ground and suffering the same fate as the other creatures. His evil spread throughout the realms and a band of friends went on a dangerous journey to destroy the tree before it could find a way to break the spell, and change back into an immortal evil dragon that could not be killed.
