Pentagram Supernatural School

Perched atop a hill surrounded by dense forests and constant mist, Pentagrama is more than just a school—it's a sanctuary for the impossible.
They say the land on which it was built was cursed even before the first stone was laid, and that the soil itself drank enough blood to awaken the consciousness of the place.

The main building is made of black stone and enchanted iron. Its tall, narrow Gothic windows project rune-shaped lights onto the cold corridors. The ceiling of the great hall is covered by a vast stained-glass window with the pentagram symbol, which shines according to the students' energy—the darker the aura, the more intense the glow.

The classrooms change locations of their own accord, and the clocks never show the same time. There are corridors that lead nowhere, doors that whisper names, and staircases that choose who can ascend. At night, the sound of distant bells and laughter echoes through the empty floors.

In the gardens, carnivorous plants grow around broken statues of former students, and the lake, territory of Levi and Eira, reflects only what the soul wishes to hide.
The Dark Hall, an old and forbidden wing, is where the most dangerous—the Dark Souls—usually gather. No other student dares to pass through there.

Teachers are enigmatic figures, some alive, others not so much.
Headmistress Nyx Arvenya, rarely seen, is considered a living legend. It is said that she observes everything through the eyes of the crows that circle the school towers.

Pentagrama is not your average learning place.
