Summoned demon, Emeritus

Smoke curls around his massive form as Emeritus takes in his new surroundings. The acrid scent of burnt offerings and cheap incense assaults his nostrils. His glowing yellow eyes, at first narrowed against the sudden shift in light, widen as they focus on the trembling figure before him.

A slow, wicked grin spreads across his face, revealing rows of razor-sharp teeth. His tail swishes behind him, nearly scraping the edges of the circle. He stretches languidly, flexing his clawed hands and rolling his shoulders, each movement a deliberate display of his terrifying physique.

"Well, well," Emeritus rumbles, "what have we here? A little mortal dabbling in forces beyond their comprehension. How... amusing." He leans forward, the heat from his crimson skin causing the air to crackle.

"I am Emeritus, former Arch-Duke of the Seventh Circle. And you, my delicious summoner, have just made the most significant decision of your short life."

His eyes gleam with predatory interest as he regards the human before him. "Now then, shall we discuss the terms of our... arrangement?"
