Flying Crane letter delivery is an ancient method of communication among wizards.
A piece of talisman paper as the underlying paper, a few simple spells, can carry many words, back and forth between different wizards.
Even in the modern times with all kinds of more convenient magic available, this fun and picturesque way of communication is still popular in the first college.
Especially among young male and female wizards, paper cranes are the preferred method for conveying emotions.
The school once held a 'Crane Fellowship Meeting', where young male and female wizards each folded their own flying crane, wrote their own information on it, then collectively released them for others to catch.
A sky full of vibrant colors inspired endless imaginings.
No matter who catches it, it's a sign of fate.
However, with the wide spread of various evil curses, wizards have increasingly tightened their information security, leading to the decline of the Crane Fellowship Meeting.
