A strange sound, like a whistle, echoed in the woods at night. The people of the North call that sound the "Demon Flute of the Forest".
Neither does Almark know what that sound is coming from. "It's the sound of the whistle of the reaper," said the traveling mage, "it's the sound of when darkness takes shape". But perhaps no one knows clearly.
However, at night, when the darkness of the forest reaches a certain degree, rarely can this sound be heard, which even children in the north know.
And that's a signal that alien demons are coming from behind the woods.
The quality is completely different from the normal demons that usually lurk in the woods.
For example, Borapa, a double-headed Phantom whose entire body is covered in black hair.
For example, Derugan, a warcraft whose upside down hair is as sharp as a blade.
For example, Malmdan, a demon manipulating strange magic with a scaled body.
We don't know the ecology, we don't know the purpose of attacking people.
It's just clear that they're intensely hostile to people. And that it's terribly strong.
Even mercenaries in the war hesitate to fight them.
Almark has come across it a few times too, but it was a horrible experience.
Even now, your whole body will be furious if you remember the ugly sounds like their roaring sounds, or the language of the other world.
Being as if man's fear of darkness had embodied it. I will do all I can to kill him, and he will disappear without coming in the morning.
I've run into a large group of them in bad luck, and I hear some mercenaries have been devastated overnight.
But surely, it was in the North Forest. I don't remember hearing that noise in the woods at night since crossing the Menover Strait to the Middle Plains.
Almark told Dr. Fier the day after Lilty's incident about the sound he heard in the woods. If they had really emerged from the woods last night, they wouldn't have been able to protect Lilty from the whole hips of Almark.
As Phea thought about something, she replied that at night, she should thoroughly instruct students not to go into the woods.
Almark himself didn't actually see the demons coming out. There is also no certainty that that sound was the same as the Northern Magic Flute. No further demands could be made.
However, since that day, another, thoughtful care of my favorite long sword, besides meditation, has been added to Almark's routine since he returned to his room.
