London Calling RPG

Athos was on duty. He attended the VIP masque because of some of the guests in attendance, and their political importance. Which meant that he was dressed in a sharp two-piece suit and wearing a lacey black and gold mask - and that he was carefully monitoring his alcohol intake. He was often found with a glass in his hand, but rarely drinking from it, although few people would have noticed that last bit.

He might be an alcoholic, but he was also a professional.
