This character uses rules from the Eberron Campaign Setting, specifically for her Dragonmark feat. However, the feat's effect is listed here, so you do not need that book to use her. Clebdecher, a famous tailor and clothing designer, is discussed in Sharn: City of Towers, where the feather fall token also appears.

As a member of a wealthy merchant house, this young woman enjoys pursuing her family's interests and looking good at the same time. But do not be belied by her decadent appearance; she is in fact a sort of social chameleon, able to drop everything and melt away into the sewers if that is what is necessary to avoid her family's many enemies, or dress up as a warrior princess to impress the local savages. With her privileged upbringing, she has had the liberty to explore her family's latent magical gifts, but she does not have the adventuring spirit. She can stay alive, but she must rely on agents to get things done.

She is lavish in her rewards and easy with her compliments, traits which endear her to her hirelings and agents. But when the going gets tough she turns cold, cool, and dangerous, and it would be unwise to presume there is anything she would not do to accomplish her goals.
