The ivory tower: Houses Elisabeth's open court, she either spends her time there, or in her private penthouse/office. Her court looks like a (red-leather and dark wood) luxurious bar with private booths than can be closed with curtains for privacy. Human blood slaves walk around, serving drinks, mingling with kindred and being fed upon. It has a small elevated platform with her large red leather seat(/throne) on it.
The court contains a 'reception hall' with a 'bar', Javier Montilla usually mans the bar if he is not doing other duties. Here you can order blood from a glass, or a 'donor' to take to , and even request some special 'flavors' added in.
