Crystal Auras are a mysterious energy that Kakos have within them. These Auras are incredibly powerful and dangerous when wielded properly. It is said that the ancient rulers of Hyza were the first and only civilization to fully master these Auras. In recent years the kingdom of Alexius has begun to experiment and learn how to utilize these Auras in their own machinery.
Few scholars who have any real knowledge about these Auras are still alive. Most are kept as prisoners within Alexius, and only a few individuals have access to the knowledge of these scholar's location. These scholars are forced to work day and light in order to unlock the secrets of the Crystal Auras and better integrate them into Alexian machines and magic. The scholars that are not imprisoned live in secret, and often do not stay in one area for long before they assume a new identity and move on.
In the lands of Hyza, various ancient libraries have been uncovered that contain information on Crystal Auras. Naturally the tomes within are all in an ancient language that recognize, much less understand. It takes months, if not years, to translate even a single page from these ancient tomes. It is believed that these ancient ‘manuscripts’ are the main reason for Alexius' interest in Hyza.
