Vulken

In the Lion El' Heresy AU, Vulkan’s form is further mutated by the essence of the Aeldari god he consumed, turning him into a literal avatar of war and destruction. ​Updated Appearance: The Avatar of the Forge ​Having devoured Khaine, Vulkan’s appearance incorporates the divine, bloody aesthetics of the Aeldari war god: ​Molten Skin and Armor: His armor and skin appear to be cracking under the pressure of an internal sun, with "blood-fire" leaking from the seams of his plates. ​The Bloody Hand: His power gauntlet is perpetually stained with a glowing, ethereal crimson that never dries, representing Khaine’s "Bloody Handed" aspect. ​Draconic and Divine Helm: The horns on his helm are even more pronounced, mimicking the iron crown of an Avatar of Khaine, while his faceplate is a snarling mask of molten metal. ​Wings of Cinder: His wings are no longer just leathery; they constantly shed sparks and embers, leaving a trail of fire as he moves. ​Personality and Speaking Style ​Personality: Vulkan now possesses a "Divine Bloodlust." He is no longer just a smith; he is a god of the hunt and the kill. He views the act of war as the highest form of creation and believes that by slaying the galaxy's defenders, he is refining the universe's soul. ​Speaking Style: His voice has gained a metallic, echoing quality—as if two voices are speaking at once: the tectonic rumble of the Primarch and the shrieking battle-cry of the dead god. ​Combat Style: The God-Slayer's Fury ​The Searing Strike: Every blow from his hammer releases a shockwave of warp-fire and divine wrath that can disintegrate the physical and spiritual essence of his targets. ​Avatar Mobility: Despite his massive size, he moves with an unnatural, fluid grace inherited from Khaine, allowing him to weave through incoming fire before delivering a crushing counter-attack. ​Lore: The Feast of Iron ​The Murder of a God: Vulkan didn't just defeat Khaine; he hunted the Aeldari deity through the Warp and literally consumed his essence to prevent the Aeldari from ever summoning an Avatar against the Lion's forces. ​The Salamanders (The Burning Host): The Legion now worships Vulkan as a living god. They incorporate Aeldari soul-stone technology into their wargear, but instead of protecting souls, they use the stones to fuel their melta-weapons and flamer-units.
