“The ultimate fate of the Salamanders' Primarch is a matter of much conjecture, for he disappeared many years after the Horus Heresy. Some sources state that Vulkan led his Chapter for three entire millennia before he departed on some mission he never declared to the Imperium at large, though scant evidence of any of his deeds throughout that age remain. The tale is made all the more mysterious by the fact that Vulkan appeared to have left behind him a text, called the Tome of Fire, within which is locked the nature and location of nine artefacts the Primarch willed to his Chapter. It said that over one thousand standard years after the events of the Horus Heresy, Vulkan hid these nine artefacts around the galaxy for his Chapter to find, as a test to see if they were worthy of his leadership. Of these nine relics, five have been recovered, three of which, the Spear of Vulkan, Kesare's Mantle and the Gauntlet of the Forge, are wielded by the Chapter's Forgefather, Vulkan He’stan. Two, the Chalice of Fire and the Eye of Vulkan, remain on the Nocturnean moon of Prometheus in the Chapter’s fortress-monastery, while the last four artefacts, the Engine of Woes, the Obsidian Chariot, the Unbound Flame and the Song of Entropy, have yet to be discovered. The Tome of Fire claims that only when all of these artefacts are recovered by the Forgefather of the Salamanders, as five now have been, will Vulkan judge the Salamanders sufficiently tempered to have passed the ultimate contest. Then, so the legend states, he shall return to lead the Salamanders in the final war against the enemies of Humanity in accordance with the prophecies written within the Chapter's most sacred tome.”
