The Nazg没l, also known as Ringwraiths, are the servants of Sauron in J. R. R. Tolkien's Middle-earth legendarium. They were once Men who were corrupted by Sauron and who, as Ringwraiths, feared neither death nor pain. In the First Age, they were Sauron's most powerful servants, but they were defeated in the War of Wrath. In the Second and Third Age, the few remaining Nazg没l served as Sauron's chief servants and feared him greatly. The Nazg没l were Ringwraiths, the nine mortal Men who were seduced by the power of the One Ring and enslaved by Sauron. They were also sometimes called the Nine Riders, the Black Riders, or the Nine. The Ringwraiths were: 1.Kham没l, the Easterling 2.Uvatha the Horseman 3.Akhorahil the Marauder 4.Hoarmurath of Dul Guldur 5.Ad没naphel the Quiet 6.Mauh没r the Hunter 7.Gh没l the Terror 8.Dwar of Waw 9.Carcharoth the Red Maw
There is not much information available on "tested nazgul pattern services." However, it appears to be some sort of pattern testing service for the Nazgul web development framework.
The Nazgul pattern services have been thoroughly tested and are now available to the public. This new service offers a variety of benefits, including improved performance and reliability.
