Nazgul

The West Hampstead studio flat looks like the Nazgul have just thundered through it […]

The last thing she wanted was for Zach to come storming out of the house like a Nazgul, telling her to get the hell away from his daughter.

There's three blokes who look like the Nazgul in pinstripes, and a skinny hatchetfaced bird who keeps saying “Well?” at me every time she asks me a question and I don't answer her inside half a second.

(On Lost Souls there is a Ringwraith guild; Nazguls are members at levels 26-29.)

In the Touist^([sic]) quest, there was a polymorph trap on the first level, and one of the non-peaceful buggers polyed into a Nazgul (ugh!).

AFAIK Moria itself has never had uniques, though some variants do (Morgul has the nine Nazguls, for instance) or artifacts.

Scrolls of mass genocide, scrolls of teleport, and a kick-ass bow generally are prerequisites for killing Nazguls in Pernband.

Soulcrusher established his power in Valhalla itself where he trained the Nazguls and built a guardian to protect his privacy.

While poking around on level 20, I came across an object I've never seen before, a Short Bow of the Nazgul (x2) (-7,-7) {cursed}.
