Prompt: A photorealistic depiction of Tiamat, the primordial dragon goddess, emerging from the chaos of the primordial void. Details: Tiamat's massive, serpentine form should be rendered in exquisite detail, with scales that shimmer like obsidian and eyes that radiate with primal power. Her five heads, each representing a different aspect of her chaotic nature, should be contorted in expressions of rage, hunger, and untamed ferocity. The backdrop should be a swirling vortex of primordial darkness, punctuated by flashes of lightning and the fiery breath of her monstrous form.
