A towering blacksmith giant hunched inside a volcanic cavern, hammering a crown out of a glowing fragment of fallen star on an anvil the size of a house. His body is a mass of dark scarred stone and cooling lava cracks, with a ring of chains wrapped around his waist and a mask of beaten iron covering his face. Sparks fly in huge arcs through the smoke, lighting the walls with streaks of orange and crimson, while tiny figures on suspended scaffolds carry buckets of embers. Deep black rock, molten orange and a cold teal glow from the star metal. Dark fantasy illustration, huge scale, dynamic action, vertical composition.
