Grayson has a somewhat complicated, or uncomplicated, past, which she has shared with exactly one person. What she does share is that she has served with the naval fleet of the First Order for nearly 13 years, the military helped pay in part for her advanced specialization in surgical techniques while advancing through medical school. She served aboard the RSD Finalizer, after being selected for service by Kylo Ren. Previous to that she served aboard the RSD Deathhammer IV.
After an unfortunate head injury caused by a group of rioters outside the FO HQ on Nar Shadda, Gray found she no longer had a place in the FO and retired (ran), just before Kylo decided to revert back to being Ben Solo.
She found herself free, retired, and joined the Explorer's Guild as a doctor and adventuress.
She enjoys relative comfort, even now as a member of the Explorers' Guild, running a private clinic for wealthy members of Nar Shadda out of her posh apartment in Parmac's Tower.
Love was found, with a former enemy of the FO, Corr Waldin, the cult leader of the Explorer's Guild and former resistance goon. Through him, and with him, she found a new way of living life, a new manner of appreciating life, and a thirst for adventure she never knew she had. He has shown her there is more to life than wine and loved her even as she helped advance the agenda of the First Order. He has been steadfast and true, and now she gets to be a part of his world fully.
Grayson is very dedicated to what she does and those she cares for, utilizing all her resources to their full measure to ensure she is benefiting her work and those she deems worthy of her caring. A strong-willed individual she is not easily pushed over, rising up to engage with those who may think her kindness is a weakness, showing that she does indeed have fangs she is willing to use. Her kindness comes easily to people at first until they prove themselves unworthy, and then she can be utterly cold and dismissive. Patience exists within Grayson to a point; she does not suffer fools. To all others, her patience can seem unending, particularly with patients. She enjoys the nice things in life and has worked hard to get where she is in her career and personal life so that she can enjoy those nice things: Fine liquors, beautiful clothing, exotic excursions and absolute freedom as a former member of the First Order.
