A wide cinematic dark fantasy view of the volcanic citadel of Muspelheim, realm of the fire giants in Norse mythology. The citadel is built into a massive black mountain surrounded by rivers of molten lava and fire pits erupting with flame. At its peak sits the Throne of the King of Muspelheim, glowing with radiant heat and flanked by stone guardians. The sky is filled with ash, glowing embers, and smoke, glowing orange and red from the reflected fires below. The ground is cracked with lava veins, and bridges of blackened stone arc over boiling magma. Distant silhouettes of fire giants patrol the citadel’s walls. The entire scene radiates apocalyptic power and mythic scale. Ultra-detailed, cinematic lighting, epic Norse mythology fantasy landscape.
