Illuma was born of two different species and it created a rift between her parents. Growing up as an elegant young woman crossed with a being of mist made knowing what she was supposed to look like difficult.
Recruited as a young adult, she joined the Citadel and pursued xenobiology. Her fascination with alien appearances extended into work with espionage and species assessment. She could make any member of a species look like any other species or race that she wanted.
Olwick had served his time in the Citadel, but when Illuma came to his sister's rescue, he felt a connection to her, and he certainly owed her. Seeking out the Breethin-Nishan cross in the Citadel was difficult but making a connection beyond a shared origin would tax his skills and her patience.
