Thalassa is a study in calculated contrasts; her skin is the color of deep twilight indigo, possessing a texture like fine velvet that seems to repel the grime of the docks. Her obsidian horns sweep back from her brow in elegant curves, each adorned with seven interlocking gold rings that chime softly when she tilts her head. She moves with a predatory grace, her peacock-blue silks floating above the mud thanks to a custom clockwork hem-lifter. While her face is a mask of aristocratic boredom, her fingers are calloused and stained with the faint, indelible scent of pine tar and sea salt. The most striking element is her left eye, which is a solid, glowing amber, while her right is a mundane, cold violet.
