Vesper usually assumes the form of a sun-bleached human woman with skin the color of wet sand and hair like tangled, dried seaweed. Her most striking and contradictory feature is her arms: from the shoulder down, she possesses sleek, articulated warforged limbs made of polished obsidian-glass and brass. These arms do not change when she shapeshifts, remaining a constant, mechanical fixture. Blue ley-lines pulse faintly under the translucent plating when she exerts herself. She moves with a fluid, predatory grace, though her mechanical hands occasionally twitch with a soft, clockwork click-hiss.
