Evan gave you this document from the onyx dragon, Afrien, containing a guide to the seal stones. The content is brief, and only people with a deep knowledge of magic can understand it. In short, a seal stone consists of three components. First, you need a medium for the continent that will act as the core of the seal stone. Second, you need five different powers. And third, a strong will to bring peace and prevent destruction must bring it all together.
