Lord Saladin Forge is a Titan Guardian and one of two known survivors of the original Iron Lords. He was one of the founders of the Iron Lords and helped end the Dark Age of Risen Warlords to establish the City Age. However, most of his comrades perished in a battle to contain SIVA, causing Saladin to dedicate his life to maintaining a watch on the Plaguelands to ensure SIVA never emerged again while also fighting to protect The Last City from threats. In time, he established the Iron Banner to keep the memory of the fallen Iron Lords alive and train the new Guardians in the ways of old.
After sitting out of the Red War due to lacking his Light, Saladin watched for several years as the Vanguard struggled against new threats and the Arrival of the Black Fleet. When the Cabal Empress Caiatl arrived and sought to subjugate humanity, Saladin was tasked by Zavala with leading a strike force to keep her from rallying her forces.

Throughout each season, Lord Saladin – one of the last living Iron Lords – visits the Tower to test Guardians in the old ways. Choose your weapons, and enter the Iron Banner to prove yourself, and earn new rewards that are exclusive to the Iron Banner activity, including armour, weapons and shaders!
In addition, Lord Saladin offers a new quest each season alongside a series of triumphs to obtain by playing in this activity. Valor is typically doubled throughout this week-long event, which helps you level up and earn even more rewards!
Iron Banner is an advanced variant of the Crucible game mode, Control, which tasks Guardians to eliminate fellow Guardians in a 6v6 setting while capturing up to three zones at a time. Having more zones nets you more points per kill, so the objective is to stay in control of multiple zones.
In Iron Banner, this is especially important, as additional modifications have been made:
Each Season, Lord Saladin will offer either a new or reprised set of Armour that you can acquire through a quest or by playing Iron Banner matches. Once you have acquired Iron Banner gear, you have a chance of getting that loot to drop from completing Iron Banner matches and/or by completing Bounties!
Lord Saladin isn’t playing around! He offers Guardians 4 bounties per Iron Banner that will reward Iron Banner Tokens, XP and +2 Pinnacle Rewards (Iron Banner Gear).
