The Hagen Mask

Once Garlinor told how he got to the City-Over-the-Abyss for an unusual festival. The whole city glowed with lights, and demons walked the streets in unusual masks.
 
Garlinor didn't know what that meant, so he started asking the locals. They, of course, were very surprised that the demon did not know the customs, but still revealed the truth to him.
 
It turned out that in the world of the City-Over-the-Abyss in the past there lived a cursed demon Sigurn. He not only destroyed his own kind, but also enslaved their spirit. No one could tolerate this, so the demons gathered a huge army and destroyed Sigurn. His spirits scattered around the world and frightened demons, so to hide, they began to wear Hagen masks.
 
Garlinor brought one such mask to the Hellsong Tavern, but the locals quickly saw through the rascal: the mask was made in a Sphere. However, she was very beautiful and Boddugan Spirit Barrel hung her in the hall as a decoration.
