Zancore Xhix's Links
Zancore created Demonica in hopes of protecting human lives, however as he began to work with her and having a friendship grow, Zancore began to realize that Demonica was becoming more and more like a daughter to him. With this, Zancore would later adopt Demonica into his family tree.
She might be an Android created by Zancore, but she always has felt like his daughter. Though she might not be on the biological family tree, she still has a family with Zancore.
Zancore is Charles' Younger Uncle and doesn't know very much of Charles. However, the two are related via blood and Zancore has always respected and honored Charles.
Charles never truly knew of Zancore, however when he did find out about him, Charles would always feel that he owed Zancore something. Charles would later watch over Zancore, along with his father Xavier, during the later events of Mass Effect 2 and Mass Effect 3.
