Felagrog, also known as Dúrin's Bane or the Balrog of Moria, was a mighty Balrog who served Morgoth since the War of Wrath that ended the First Age, and only the Elves and the Wise (including the Istari) knew of them beyond the oldest tales and dimmest rumors. The Dwarves that reentered Moria near the end of the Third Age had dug deep, and uncovered Felagrog from its self-induced coma in hiding in the roots of old kingdom. Aroused and rested, Felagrog once again felt his power and pride; perhaps, too, he felt the Power of its Lord's lieutenant, Sauron of Mordor, reaching into the world. He killed two of the Dwarf-kings and gathered to itself a mighty army of Orcs and Trolls from the surrounding area by the force of its will alone. With these troops, he drove the surviving Dwarves from Moria and established itself as the ruler.
Centuries later throughout the Third Age, Felagrog was encountered by the Fellowship of the Ring in TA 3001 when they passed through Moria. As the Fellowship fled across the Bridge of Khazad-dûm, Gandalf stopped to hold off the demon. The wizard's magic was enough to destroy the bridge and topple the Balrog into the chasm below, but the demon's fiery whip ensnared Gandalf, bringing the wizard with him. After chasing the Balrog through miles of tunnels to Dúrin's, Gandalf smote Felagrog and ended its foul existence. The wizard also died from his wounds, but was soon revived as Gandalf the White.
