Trident (Iron Warriors) - Notable Triarchs: Kydomor Forrix - Forrix, called "The Breaker," was the first captain of the Iron Warriors Legion.Erasmus Golg, Warsmith of the 11th Grand Company - Erasmus Golg was the captain of the Iron Warriors 11th Grand Company during the Horus Heresy. Following his Primarch's Edict of Decimation, Erasmus Golg strove to epitomize the ruthless efficiency that Perturabo sought in his warriors. Golg was a brutal commander whose only punishment for failure was death. He eventually ascended to the prestigious Trident alongside Warsmiths Forrix and Harkor. Deemed flawed but useful by his primarch, Golg was placed in command of the battle barge Contrador during the Heresy. During the Battle of Phall, Golg was one of the primary Iron Warriors commanders, but in the closing stages of the battle he was killed by the Imperial Fists Captain Alexis Polux, who also took control of the Contrador. His place on the Trident was later filled by Barban Falk.Harkor, Warsmith of the 23rd Grand Battalion - Harkor was warsmith of the 23rd Grand Battalion and a member of the Trident until the close of the First Siege of Hydra Cordatus, when Harkor ordered his forces to make a bloody but successful push against the Imperial Fists defending the Cadmean Citadel. While Harkor's orders did lead to the close of the siege, his forces were largely bogged down and the attack cost his Grand Battalion many needless casualties, as well as disobeying Perturabo's direct orders and battle plan; Harkor was summarily stripped of his rank by the uncompromising Lord of Iron. Harkor's position as warsmith and membership of the Trident were immediately filled by his former subordinate Kroeger.Barban Falk, Warsmith of the 126th Grand Company - During the Horus Heresy, Barban Falk was a warsmith of the 126th Grand Company who was part of Perturabo's select triumvirate of advisers called the Trident and was known for his abnormal and imposing size and strength, even for an Astartes. He was appointed to serve as a triarch alongside Kroeger in the aftermath of the First Siege of Hydra Cordatus and Battle of Phall  that saw the Trident's Harkor and Golg disgraced and slain, respectively. Later it was during a pitched battle in the depths of an Aeldari tomb citadel that Falk was contacted by a Daemonic entity. He used the Warp entity's power to focus and command his Iron Warriors. After the escape from the Aeldarir tomb world of Amon ny-shak Kaelis, First Captain Kydomor Forrix called Falk by name, and Falk replied, "I no longer know that name, I am simply the Warsmith." By the time of the Siege of Terra Falk had become aloof from most material concerns, insisting on simply being referred to as "The Warsmith" and scoffing at the demands or goals of his superiors such as Forrix. Forrix feared that like the Daemon Primarchs, Falk's true loyalty lay with Chaos' broader agenda for the galaxy and not with simply gaining victory over the Loyalists on Terra.Kroeger, Warsmith of the 23rd Grand Company - Kroeger was a warsmith and later captain of the Iron Warriors Grand Company under the command of Barban Falk, "The Warsmith," during the Siege of Hydra Cordatus. Kroeger originally served as a trooper in the 23rd Grand Battalion under the command of Warsmith Harkor during the Horus Heresy. After Perturabo stripped Harkor of his rank for disobeying orders during an assault on an Imperial Fists citadel on Hydra Cordatus, Kroeger was promoted to Warsmith and given a spot in the Trident, passing over Toramino. Kroeger proved to be an outside-the-box thinker while on the Triarch, often preferring the most brutal and simplest tactical options, a concept that appealed to Perturabo after the Battle of Phall. He still retained much of his sense of honour, being disgusted by the corrupted state of the Emperor's Children Legion after they were consumed by the worship of Slaanesh. Kroeger did not want the position he was promoted to, and was the victim of the constant scheming of the ex-Triarch Harkor. While on Iydris, Kroeger began to succumb to a level of bloodlust despite attempting to protect Perturabo from the machinations of Fulgrim. In a frenzy while fighting Aeldari Wraithguard, his forces slew Harkor. During the Siege of Terra Perturabo placed Kroeger in charge of the operation to capture the Lion's Gate Spaceport, something which shocked Kroeger's fellow Triarch Kydomor Forrix. Perturabo appreciated Kroeger's bluntness, and hoped that he could use it to subvert Rogal Dorn's expectations that the Iron Warriors would unleash a complicated assault plan. Kroeger's initial offensive failed in the face of the Emperor's psychic shield that wrapped around the Imperial Palace, but as part of the operation Forrix and 1,000 Iron Warriors were sent behind enemy lines as part of an infiltration operation. During the renewed attack on the Lion's Gate Spaceport, Kroeger engaged Imperial Fists commander Fafnir Rann in combat and wounded him. Over time, Kroeger's blood lust only grew stronger, until he finally became a Khornate Berserker in service to the Blood God in the centuries after the end of the Heresy.
