MineArchiveDurin's Bane
Fictional record. This page describes an incident from a fictional setting, not a real event. Information is based on the cited canon, with adaptations and interpretation distinguished where necessary. It is kept separate from the real MineArchive corpus — see Fictional.
| Date | T.A. 1980 |

| Mine | Khazad-dûm |
| Primary type | Other |
| Associated types | Fire |
| Fatalities | 2 (The primary texts name two dead individually — King Durin VI and, soon after, his son and successor Nain I. No total figure is given for the wider death toll among the Dwarves during the flight from Khazad-dum that followed, which was almost certainly higher.) |

Dwarves delving for mithril in the deeps of Khazad-dum broke into a place where a Balrog of Morgoth had lain hidden since the First Age. It killed King Durin VI, and his son Nain I in turn soon after, ending nearly the whole of Durin's Folk's presence in the realm within a matter of years.
Cause
The Dwarves of Khazad-dum, working the mine's deepest levels in pursuit of mithril, dug far enough to break into ground where a Balrog of Morgoth — a being of fire and shadow that had escaped the ruin of Thangorodrim at the end of the First Age — had lain hidden and unnoticed for thousands of years.
Contributing factors
No warning sign or precedent is recorded; nothing in the primary texts suggests the Dwarves had any way of knowing what lay beneath the workable ore, and no fault or specific decision beyond the general drive to keep delving deeper for more mithril is identified as a cause.
What happened
As the more easily reached seams of mithril were exhausted, the Dwarves of Khazad-dum pushed their workings deeper into the mountain. In T.A. 1980 this delving broke into the hiding place of a Balrog, a fire-demon of the First Age believed lost with the fall of Morgoth's stronghold of Thangorodrim millennia before. It killed King Durin VI. His son Nain I took the throne and was in turn killed by the creature shortly afterward. With two kings dead in quick succession, Durin's Folk abandoned Khazad-dum rather than continue to contest it, fleeing the realm their people had held since the Elder Days. The creature itself remained in the depths for the rest of the Third Age, and the name Khazad-dum fell out of use among those who remembered why it had been abandoned, replaced by Moria — the Black Pit.
Rescue & recovery
No rescue attempt is recorded. Durin's Folk's response was to abandon the realm entirely rather than attempt to recover it or confront the creature again.
Investigation & inquiry
No formal inquiry of any kind is recorded. What is known of the event comes down entirely through Durin's Folk's own oral and written tradition, as preserved in the Third Age records drawn on by Appendix A.
Aftermath
Durin's Folk did not attempt to resettle Khazad-dum for the rest of the Third Age. The one recorded attempt to reclaim any part of it — Balin's expedition of T.A. 2989-94 — ended in the colony's destruction by Orcs, not by the Balrog itself. The creature was encountered once more, in T.A. 3019 — see The Bridge of Khazad-dum, below.
Consequences
No specific change to Dwarvish mining law or practice is described in the primary texts. The practical consequence was total: the sole abandonment of Khazad-dum itself, which Durin's Folk did not permanently resettle until Durin VII returned in the Fourth Age.
Memorials & commemoration
No memorial to the T.A. 1980 dead is described in the primary texts. Balin's own tomb, in the Chamber of Mazarbul, commemorates the much later, unrelated destruction of his T.A. 2989-94 colony by Orcs, not the original disaster.
Canon & adaptations
Amazon's The Rings of Power moves the Balrog's stirring into the Second Age, during Durin III's (or, in some tellings, Durin IV's) reign, when an Elvish leaf is dropped into a newly opened abyss — thousands of years earlier than Appendix A's T.A. 1980 date, and under a different king than Tolkien's own Durin VI. This is a significant, well-documented adaptation change to the timeline, not a variant reading of the same book text, and is kept here strictly as such.
