A Ancient Demon

In the shade of the trees, away from the light of the clear camp, Luke watched Alexis and the emissary act. At one point, Tenth took a notebook from his bag, flipped through a few pages, and showed it to the woman.

Soon after, he moved a few feet away from the circle. The half-dragon walked to the circle's center and placed the white cube on the floor. She didn't seem nervous, but in return, the emissary was even biting his nails.

"Release," Alexis said, low enough for only her to hear. Seconds later, the cube began spouting white flashes. 

In the blink of an eye, the flashes became more intense, and as they intensified, the cube doubled in size. 

When the cube finally exploded into small white particles, the figure of a demon appeared. Unlike the endearing figure with red skin and long horns that is widespread, demons are macabre and confusing figures, which desperately try to copy human traits.
