Great Sword of Shaggyism

The Great Sword of Shaggyism is a sword stuck in a certain rock in Ireland. Currently science shows that this is the only sword capable of slaying the greatest enemy of the Shaggy Empire, Verde. Whoever is able to break the sword free of the rock, will become a hero and go on a quest to slay Verde once and for all. If this hero succeeds in this quest, they will become a great legend and be remembered for eons. So far, nobody has been able to pull out the sword for more than 5 milometers, but if someone pulls the sword out of the stone, they will become a great savior.
