“He be the 5th King o' Mithril Hall, reclaiming the Hall himself with a few powerful friends, he road the shadow dragon Shimmergloom into Garumns Gorge, both covered in flaming oil and Bruenor hacking wildly into the dragon's spine. Over the next few weeks, Bruenor worked his way up from the lowest points of Mithral Hall, covering his beard and hair in ash to disguise its color from the duergar that now resided there. The old warrior killed any gray dwarf who found him out, and any he caught alone in the tunnels and chambers of The Hall. Eventually, he escaped by climbing up a chimney shaft--during the process of which he was attacked by a giant spider. Though he was bitten, Bruenor managed to kill the spider and find his way up to a vent to the outside. Finally overcome by the poison, Bruenor lost consciousness. After regrouping with his friends an' many reinforcements, they went back to their home in the North, and spent the winter gathering up forces to take back Mithral Hall. During their efforts to regain this lost dwarven stronghold,
Bruenor and his armies drove out the duergar, and Bruenor was set up as King of Mithral Hall, with a couple of thousand settlers from another dwarven kingdom swearing their allegiances to him.
The peace was short-lived, though, as a small party of drow, seeking Drizzt, caused the apparent death of Wulfgar. In the skirmishes during this, Bruenor lost an eye.
The death of his adoptive son Wulfgar sent Bruenor into a profound depression. When Drizzt left to go to Menzoberranzan to settle accounts with his people, Catti-brie saw Bruenor as being too engrossed in his own grief to a useful companion when she chased Drizzt. When she and Drizzt came back, months later, their news of a planned drow war on Mithral Hall forced Bruenor out of his depression.
With aid from neighboring kingdoms and people, Bruenor and his kingdom survived the assault upon Mithral Hall. Bruenor and his friends even set themselves to seeking out the leaders of the drow army--the Matron Mothers of the most powerful houses. In the battle upon their meeting, Bruenor--with much difficulty--killed Matron Baenre, ending her centuries-long rule of the drow city. After the battle, they found Gandalug--the founder of Mithral Hall and Bruenor's ancestor--who had been Matron Baenre's magically-held prisoner for almost two millennia. The discovery of another legitimate king allowed Bruenor to abdicate to his ancestor and pursue his own ambitions in Icewind Dale and the mines his clan had made there.
During Drizzt's and Catti-brie's six-year absence from his side, Bruenor became closer friends with Regis. He also had a cleric attempt to restore his lost eye--which succeeded, albeit gradually.
When the balor Errtu gained the Crystal Shard, Bruenor joined his friends to defeating the tanar'ri. At first, Drizzt and Bruenor were overmatched owing to Errtu's magical abilities, until Wulfgar regained Aegis-fang and joined the battle, allowing them to win. As it turned out[attribution needed], Wulfgar had not been killed six years before--rather, he had been taken to the court of the drow goddess Lolth, who traded him to Errtu in exchange for Errtu's services to her. Errtu then spent years torturing Wulfgar and seeking a chance to cause Drizzt to release Errtu's banishment. After Drizzt accidentally released the banishment, Errtu brought Wulfgar back to the Prime Material Plane to witness his friends' destruction. The arrival of Aegis-fang, however, allowed the friends to destroy the demon, again banishing it for a hundred years.
Bruenor is also one of the main characters in the Drizzt-centric "Paths of Darkness" novels where he is often the supporting father figure to a struggling Wulfgar after his torment in the Abyss.
In "The Hunter's Blades" trilogy, Bruenor returns to reclaim the throne of Mithril Hall after the death of Gandalaug Battlehammer. In "The Thousand Orcs" Bruenor suffers a near-fatal blow and his life stands on the edge of a knife for most of "The Lone Drow", being kept alive only by a constantly labouring team of Dwarven priests. However Bruenor is brought out of his near-comatose state by the halfling Regis who uses his magical gem to persuade Bruenor to aid his fighting kin. In "The Two Swords" Bruenor finally reclaims his rightful throne and leads the dwarfs in the defense against King Obould and his army of orcs and frost giants.
