Effran is a slender tiefling with pale crimson skin and two small obsidian horns that curve sharply back against his skull. He has solid, golden eyes that lack pupils and a long, thin tail that often twitches when he is nervous. He wears tattered grey acolyte vestments over a set of modest leather armor, and he always carries a heavy satchel full of ink-stained papers and old books.

Effran is exceptionally soft spoken and academic. He prefers the quiet company of a library to the chaos of a tavern. Because of his sheltered upbringing in a temple, he is often naive about the ways of the world, but he possesses a fierce, hidden curiosity about forbidden lore that he hides behind a mask of clerical politeness.

Effran was raised within the silent cloisters of a great cathedral, serving as a lowly assistant to the head librarian. While his peers studied the light of the gods, Effran was tasked with the maintenance of the basement archives where the more problematic texts were kept. He lived a life of isolation, tolerated by the priesthood but never truly embraced because of his infernal heritage. His days were spent dusting shelves and his nights were spent reading about the cosmic entities the scrolls described. One evening, frustrated by the silence of the divine and his own physical frailty, Effran discovered a singular page that seemed to speak directly to his soul. It was not a prayer, but a contract. The voice that echoed in his mind when he read it offered him the strength to see the world beyond the cathedral walls, something no god had ever granted him. He accepted the pact, seeing it not as an act of evil, but as a practical necessity to find his own place in a world that saw him only as a monster. Now, Effran has left the temple behind, carrying his scrolls and his new, dark power into the unknown. He seeks to balance the morality of his upbringing with the demands of his patron, hoping to prove that he is more than just a servant of the stacks.
