Lucifuge, or Lucifuge Rofocale, is the Prime Minister of Hell according to the Grand Grimoire, Lucifer granting him power over all worldly treasures. He counts the Goetic nobles Bael, Agares, and Marbas among his direct subordinates. The Grimoire's initial spells (as in the ones that must be done before the magician can do anything else, or at least any other conjurations) require the magician to first bind Lucifuge to a pact, which involves a fair amount of risk on the magician's part--if he does not give Lucifuge a small portion of every treasure he attains, show charity to the poor, and keep the pact's existence a secret, Lucifuge can take his soul for himself.
"Lucifuge Rofocale, whose name means "he who flees the light", is the prime minister of Hell, watching over the government. He is Demon Lord Lucifer`s counterpart. On his head are three twisting horns, and he has a goat`s body with a long tail. Lucifer ordered him to manage the world`s fortune, and he has Bael, Agares, and Marbas at his command. He is also an officer of contracts, granting his conjurers` wishes in exchange for their souls."

Lucifuge is a general of Lucifer's and appears as a boss in Lucifer Palace. On the Law Route he tells Flynn that he praises a false God, who he has sold his very soul to and that he is worthless. In the battle he calls him a puppet to authority and thus do not deserve to be counted amongst the living, so he shall remove him in order to make a ideal world. During the Neutral Route he says he respects the fact that Flynn accepts a world of chaos, but cannot accept God's order. Lucifuge views his soul as valueless due to the hope within Flynn as he starts the battle. In battle he tells that their aim is the total elimination of all order in the universe and that he will personally dispose of Flynn. As he dies in both routes, Lucifuge's only words is to apologize to his master and ask that he reclaim what is rightfully theirs.
Lucifuge is fought in Ice Book in the Ice Fortress north of the Ice Apostle's Palace, blocking the underground path that leads to his masters palace. He will later be revived after beating the game and can be found in the Seele Plains.
