There isn't much to say about this ring. It once belonged to a Wizard whose name is Studdepac. He was a German wizard and practiced the ancient ways of Germanic magic, including original Celtic bloodline magic. The original Celts eventually migrated their way inland and became what would be known as the Germans and Slavs today.
This ancient magic is extremely powerful because it's based in cosmic magic and the magic of the universe. It is called Cosmogenic magic because it deals with the origins of magic and being to create your own, which is what the energies and power of the Cosmos will do for you. However, in order to use the Cosmic energies, you must be able to harness those energies from the universe. That's what this ring does for you.
When you wear this ring, Studdepac will be present, because he is currently in soul form. He will guide you along your journey and he will allow you to create whatever kind of power and magical abilities you want That's the whole point of it being Cosmogenic magic. You call the shots. You decided what you want. This piece will handle the rest.
