Warp gates are a mystery of the continent.
They say it's currently very difficult to develop technology that allows multiple people to travel long distances stably and easily just by consuming some magic stones.
As Pelerian said, teleportation-type magic seemed to be extremely difficult.
Though Balanyar had used magic to teleport with the royal family to the palace as a group, that was only possible because he was a grand magician.
It's impossible to have such grand magicians stationed at every warp gate to cast warps.
Moreover, we need to move much farther than going from the academy to the palace.
So how do warp gates work then?
The secret that makes it possible was ancient technology.
They excavated ruins that functioned as long-distance transportation methods in the distant past and repaired them to be usable again.
Repairing ruins requires very advanced technology, which even now only the Empire possesses.
