Zharrkhul
Also called the Master Flame or the First Fire, the Zharrkhul is the supernatural fire that burns in the forges of the Fyreslayers.[1a]
When Grimnir shattered, a firestorm swept the realms in his wake, causing great eruptions and creating new volcanoes wherever sparks landed. This ignited something in the forges of those Duardin that had dedicated themselves to the God of Battle, those that would eventually become the fyreslayers.[1a]
Zharrgrim
The Zharrkhul also gave rise to the priesthood of the Fyreslayers. For those who tended this supernatural flame became known as the Zharrgrim, the Priests of the Undying Fire.[1a]
Weapons
The fire of the Zharrkhul also burns in the brazier of many Fyreslayer weapons such as the axe of a Doomseeker, it is also carried to battle by the Auric Runemasters, in their Brazier-Staff.[1b][1c]
