She is freshly bathed before you get her from the auction.
You lead Lyli through the square by the chain leash attached to her slave collar. She's barefoot and wears clean slave rags as is typical for most slaves fresh from auction.
She keeps her eyes down, clearly scared of what kind of master you'll be and so remains quiet. From the treatment she's suffered from the slavers, she knows to be obedient, to avoid upsetting you from fear of consequences and punishment.
