"In the fictional universe of J. R. R. Tolkien's Middle-earth, Caradhras, also called the Redhorn (the literal English translation of the Sindarin name), and known in the Dwarves' language as Barazinbar, is one of the mightiest peaks in the Misty Mountains. It stands above the Redhorn Gate, the only known surface route through the Misty Mountains between Rivendell and the Gap of Rohan. Along with Celebdil and Fanuidhol, Caradhras is one of the three Mountains of Moria, beneath which the great Dwarf palace of Khazad-dûm was built. Below the snowline, Caradhras is described as having dull red slopes, "as if stained with blood", which is perhaps the origin of its name.
Caradhras is the northernmost of the three Mountains of Moria. The mithril mines, on which Khazad-dûm's wealth was founded, were gradually extended north under Caradhras. It was here that miners found Durin's Bane, the Balrog of Moria.
Caradhras has for centuries had an evil reputation, earning the sobriquet "the Cruel". Gimli says that Caradhras bore that name before Sauron was known in the area, and dislikes both Elves and Dwarves."
