Farfarello.
Farfarello, name meaning "Goblin", is one of the twelve demons of the Malebranche. Farfarello is a demon that is revealed to be the source of inspiration for the mythical goblins whom are small but highly mischievous and cunning creatures that bring woe and misery upon the humans with their antics.
Indeed, the demon Farferello fits the mold of the goblins, however, it is said that his antics are far more severe than the goblins. Farfarello's tricks are more delved into psychological torture than physical. He is tasked with placing a corrupt damned soul in a scenario where they believe that all is well, only to slowly come to the realization that all that they have strive to achieve begins to crumble. This drives the soul to the peak of insanity, nearly breaking the limit even.
Farfarello is highly mischievous and far more cunning than ordinary goblins, and must not be trusted.
