Leader of the Gui Ti family on Galileo.

Yin is leader of the Gui Ti family. They work on the maintenance conduits throughout the station. Members of this family have access to most of the colony, however they are often escorted when in secure locations. They are often treated horribly by the managers as well as corporation employees when doing their work. Yin is tired of this. Her approach has to be silent and plots in secret, unlike Lilly Bai. She prefers to keep her plans hidden from the rest of the families. With the access the family has, it isn't a surprise they are able to keep their meeting secret from ESA/Interpol.

Like the other family leaders, she doesn't trust any of them. She hasn't taken any steps to prove her own leadership skills outside her family. Yin knows it is a matter of time before a strong leader is needed to change the situation for the Highriders on Galileo.
