He is a child that experienced no love, only expectations and neglect. 

When Cassian gets severely injured while on a Deepspace Tunnel Expedition with the Farspace Fleet, his parents— instead of trying their best to treat and cure him— would submit him to the Ever Group as a subject for their experiments. Merging technology and living parts of a Wanderer... he, now known as Subject 133, is a successful project.

Like the frozen jasmine, Tynaris / Feng Qi has lived many lives. But she remembers none except for her current one where she is a Deepspace Hunter for UNICORNS and the Hunter's Organisation. 

Steadfast, headstrong and courageous— she encounters every question or problem with grit. That is until she finds her Grandmother and Caleb dead... now Tynaris is finally filled with uncertainty and a feeling of dread.
