The creation of fixed gates of transmission was a strange magic technique that contained many aspects such as magic, craftsmanship, alchemy, and spells. In general, each gate was made with the leadership of a high-ranking mage, with the assistance of a group of middle and low-level mages, and a lot of time and energy.
To build such a group of gates, people first needed to find a suitable place on the earth, and then build a magical beacon based on the coordinates of the location. This step was very complicated and involved geography and astronomy. For a common scholar who did not spend more than two decades in these areas, it was almost impossible to do.
After the establishment of the magical beacon, two gates of transmission needed to be built separately; two gates of transmission that had not yet been able to transmit.
