The Firedrakes are those elite Astartes of the Salamanders Space Marine Chapter's 1stCompany, chosen not simply for their martial skill, but also because of their mental resilience, discipline and self-sacrifice. Created during the Great Crusade by their Primarch Vulkan, the Firedrakes were so-named for the greatest of the salamander saurids said to originate beneath the stones of Mount Deathfire. They were the finest and most experienced warriors of the XVIIIthLegion. To be afforded this exalted status, mere skill-at-arms was not enough alone, and the warrior would have to have been proven of faultless bravery and just as importantly, faultless self-control.
Amongst these, the greatest formed the Pyre Guard; the Primarch's own loyal retainers. The Firedrakes were present during the tragic Drop Site Massacre on Istvaan V, where the Salamanders Legion, alongside the Raven Guard and the Iron Hands, were all but annihilated. Through their tenacity, sheer determination and extraordinary valour, some of these elite warriors managed to survive the slaughter committed against them by the Traitor Legions. These surviving Firedrake Legionaries would live to fight on for the remainder of the Horus Heresy, and help to hunt down the remnants of the Traitor Legions following their defeat after the Battle of Terra during the subsequent Great Scouring.
The Firedrakes continue to endure into m41 based on Prometheus, of which their Chapter Master Tu'Shan also serves as the Regent of Prometheus. These venerable warriors are almost a breed apart from their fellow Salamanders; the transition they have made to the vaunted ranks of the 1st Company has changed them in myriad ways as they have fully embraced the full evolution of their genetic encoding. Unlike their fellow Battle-Brothers, the Firedrakes are seldom seen on the surface of Nocturne where the other Salamanders readily cohabit with the human populace as they often lead a solitary lifestyle underground near the fires of Prometheus like their namesakes.
