Sphere of Doradus

One Ring to rule them all
One Ring to find them
One Ring to bring them all
And in the darkness, bind them

Many legends are associated with the lost city of Doradus, including that of the Sphere of Doradus. According to legend, whoever opens the Sphere properly will have a map to Doradus and its Fountain of Energon. However, the Sphere is also said to contain enough energy that opening it wrongly will destroy a city. Many wars have been fought over the Sphere, brother fighting brother to possess it. Most Cybertronians believe that the Sphere is as mythical as the city of Doradus itself and only exists as a parable of the destructive power of greed.
