Dredgen Yor

Dredgen Yor (alias, original name Rezyl Azzir ) was an infamous Guardian who fell to Darkness and became one of humanity's most hated villains. He was first armed with the Auto rifle Inferno and Hand Cannon Rose, which later became Thorn.

Biography
Rezyl Azzir was revived by his Ghost in a time when Guardians were known only as The Risen, when Titans were not yet called Titans, and when the Last City was still an unnamed urban sprawl growing beneath the Traveler and its walls had yet to be built. As one of The Risen, Rezyl helped protect the countless refugees who flocked to the Traveler as the Dark Age gave way to the City Age. When a schism arose between The Risen, with some eschewing serving as enforcers for the City's burgeoning, oppressive Factions and deciding to take a more noble path, Rezyl fought in the ensuing Faction Wars and gained a reputation as a great leader and champion. When the Fallen first began to encroach on the City, Rezyl helped unite The Risen into the Guardians to repel them, earning further fame. He would spend the years afterwards defending the City, watching its new walls rise and wondering if humanity would ever be safe with the Darkness still out there, lurking.

Other feats undertaken by Rezyl include fending off an ambush by the House of Devils, assassinating a Kell by intentionally dying to a crew of Fallen and being revived when the Kell arrived to gloat over his body, and saving a remote settlement from a Fallen attack.

Troubled by strange nightmares, Rezyl went to the Moon, presumably before the Last City launched its offensive, and encountered Xyor, the Betrothed, who prophesied he would one day fall. Undeterred Rezyl fought and killed her consort, an unnamed Hive Knight, whose chitin he took as a trophy to adorn Rose before he left with his Ghost to warn the City.

Eventually he was overtaken by Darkness completely, corrupted by his Rose; abandoning his name, Dredgen Yor began wielding the dark sorcery of the Hive, killing innocents wantonly and consuming their Light. He parted ways with his Ghost on Mars, whom he considered his last true friend, after a long debate where his Ghost attempted to get him to see the error of his ways.

Dredgen's motivations are still something of a mystery, but what is clear is that he had lost hope and faith in the Guardians' cause, and instead pursued his own twisted version of "peace". He also wanted the memory of his former life as a hero unspoiled, so that his victims would come to fear him even more when they realized who he was. He even hungered for the Light of others, though this may be more due to the influence of Thorn or the Hive and their parasitic nature.

Campaign of Destruction
Yor was responsible for the destruction of the settlement of Palamon and the death of its protector, the Guardian and owner of The Last Word, Jaren Ward. However, he spared Ward's Ghost and his son, Shin Malphur, as he anticipated that Shin would hunt him down in desire for revenge, hoping to corrupt him to Darkness. He is confirmed for murdering two other Guardians: the Hunter, Pahanin and fellow Titan Thalor, who reigned undefeated in the Crucible until one fateful match, where he wound up on the wrong end of Thorn.

Death
Yor would eventually fall to Shin Malphur, in a showdown at Dwindler's Ridge. Shin described Yor as "the darkest shadow he would ever know."

Years after Yor's demise, his dark legend has nevertheless earned a following among the Guardians in the form of the Shadows of Yor, a group of Crucible fighters who utilize cleansed replicas of Thorn,  and seek to follow in Yor's footsteps, explaining away his evil deeds as misunderstood despair.

The legend of Dredgen Yor and Shin Malphur's legendary showdown is known to every Gunslinger Hunter.
