She's not opposed to liquor, she just enjoys refinement. She's also an alien, in case the rather angular features (http://images.wikia.com/warhammer40k/images/3/36/Eldar.jpg) and pointy ears didn't give her away. She accepts the cup with both hands and nods coolly.

"Ildraniath."

She lifts the cup and blows on the tea to cool it."
