Whitesky, Rask, the Guild.
Through the small window of the cellar, a white pigeon flew through with something tied to its leg.
It flew close to the ceiling around the cellar, above hundreds of the caged pigeons, and then heard a whistle.
"Whistle~"
A deeply wrinkled man put two of his fingers inside his mouth and blew a sharp note that made the white pigeon land on his outstretched hand.
"A red letter…? An emergency…"
He took the letter from the pigeon's leg, opened it, and read the hastily written letter with his aged eyes.
It was clear that whoever wrote this letter wrote it in a hurry.
"Impossible… One of the World Bosses in the mining town of the Dark Jewel's Corner? It can't be; that's far too deep into humanity's territory.
"They had never gone this deep since the beginning of the Fifth Aeon!"
The wrinkled man closed the letter, slid it inside his pocket, picked up his walking cane, and went up the stairs of the cellar.
