In the world no longer airplanes became a thing of the past. Wizards who combined their knowledge with science and engineering created an almost instantaneous means of transportation called "Teleportation Crystal".
For its use, a mage of 5th level and above is necessary, due to the high mana cost it requires. Approximately 1000 people can be teleported a maximum distance of 9000 kilometers in only 5 minutes. Teleportation is only possible to a place where a teleportation crystal exists.
The teleportation crystals are guarded by specialized offices similar to the old airports.
