From Destinypedia, the Destiny wiki
In the first years after the Collapse, a time before the rise of the Vanguard and the Last City, some of the earliest Guardians to be revived chose not to protect the world, but subjugate it. Taking over various parts of the planet, some Guardians became Warlords and injustice reigned, with the rest of the populace living under the tyranny of the various factions. Eventually, Guardians with integrity chose to stand up to their tyrannical brethren and form the Iron Lords. More and more noble Guardians joined the cause until an army hundreds strong was formed and the oppressive warlords were deposed, along with the Fallen who ravaged the Earth. One former Warlord, Lord Felwinter, was swayed by the Iron Lord's message and decided to join their cause.
Following the Warlord conflict, the Iron Lords dedicated themselves to defending survivors of the Collapse and restoring civilization. The Iron Lords protected the newly constructed walls of the City in the infamous Battle of Six Fronts against six Fallen approaches, and not a single front faltered. During this conflict, the Iron Lords were known for their invincible patrols and their contributions to the great Wall-Building, cementing their legend.
Seeking a way to rebuild what was lost during the Collapse, they eventually found SIVA. Hoping it would be able to build ships and colonies, the Iron Lords pushed through the Cosmodrome despite Rasputin's desperate attempts to sway them and suffered the loss of hundreds of Lords to a combination of aerial strikes, a Frame army, and SIVA constructs. Ultimately, the venture would result in the loss of all save for Saladin Forge and Efrideet, who had disappeared to live in the wilds beyond the city. The eight Iron Lords who made it, save for Lord Saladin, sacrificed themselves to contain the biomechanical plague by sealing themselves within its replication chamber before it had time to escape. The sacrifices of the most well-known Lords are honored at the Iron Temple atop Felwinter Peak, and celebrated in the Iron Banner tournament. The names of their signature weapons are lent to various Iron Banner equipment, such as the Felwinter's Lie Shotgun and the Jolder's Hammer Machine Gun. The second generation of the Lords, the Iron Wolves, and their weapons are likewise honored by the Iron Banner.
The Iron Wolves were a group of Guardians who were the Iron Lords's second generation after their inception and came to the Last City's defense during one of its darkest hours. Like their counterparts, the Wolves were felled in what would become The Plaguelands during the first war with SIVA. The Iron Banner tournament is held in honor of both the Iron Lords and the Iron Wolves.
The New Age of Iron lords
After the destruction of the SIVA Crisis, Saladin Forge knighted The Guardian and names them the first of the new generation of Iron Lords setting out to rebuild the Iron Lords and once again create a beacon of hope for the Last City.
