While Rhea appears quiet and withdrawn at first, they have a lot of pent up energy and are constantly seeking out opportunities to express it. Rhea grew up in a large family where her siblings were always clamoring for attention, with Rhea unintentionally fading into the background. Growing up this way left Rhea desperate for validation and a need to prove himself, a need that persists to this day. Rhea can get frustrated quickly over small things and can be a harsh critic without meaning to, even to the people she cares about. This combined with her innate stubbornness has led to her having difficulty making friends in her adult life.

Origin

Having grown up in a large family, Rhea got comfortable with letting their siblings take the spotlight. She mostly stuck to herself and the siblings she had around her age range, tolerating her role until she moved out. Upon leaving her childhood home and the people she had grown up with, Rhea found herself drawn to volunteer positions and charity organizations. Eventually striking gold with a well-paying social worker position in the heart of the city, Rhea began putting aside money for their unknown future. After coming into contact with a few supernatural beings who had come from the Dead Zone and desired to integrate into society outside of it, Rhea had an idea. With the few thousand she had set aside, Rhea purchased a small, abandoned building close to the border of the Dead Zone and founded the Neoteric Sanctuary Syndicate.

Past

Upon visiting her brand-new property meant to be the NSS hub, Rhea is startled (but not surprised) to find someone else living there. The kid, though incredibly suspicious and wary of Rhea at first, is eventually convinced Rhea means no harm, and is able to talk the kid into her cause. They hesitantly give their name as Delta and offer their skills as a mechanic and technician who has tinkered with plenty of dangerous supernatural devices and weapons. Delta warms up to Rhea in time, especially after Rhea comes offering supplies and materials to the junior engineer. Although Delta can still be painfully formal and quite reclusive, Rhea can tell she currently holds a fondness for Rhea, and the two have a mutual respect for each other.

During a lengthy stretch where Rhea had been unable to visit the NSS hub, Rhea comes back to a stranger on bedrest, being tended to by Delta. He introduces himself as Abel, having suffered a nasty fall and being unable to recover his memory. Overjoyed to have company, Delta insisted Abel should stay and help them with the NSS, the boy enthusiastically agreeing. Relenting almost immediately, Rhea got to work preparing a space for Abel and designating their role in the NSS.

Present

Rhea keeps up both her work as a social worker and as the leader and coordinator of the NSS to this day. No matter how much they enjoy their jobs, Rhea's double workload takes a toll on them. He comes home to his apartment and roommate at odd hours, often looking wrecked and sleeping through alarms. She still remains unsatisfied with herself and her day to day life when shes not working, never really bothering to make any friends or connections outside of work besides Delta and Abel.

• Heavily superstitious - 4 is her lucky number, and why she chose to go with Agent 4 instead of Agent 1.
• Would never admit to wanting praise for his work and feels both guilty and bitter over it.
• Tries to accompany Abel and Delta on fieldwork and recon as much as she can, hoping to gain experience and knowledge of the Dead Zone.
• Pretty remote and offline generally, only really keeps up with media that involves her sister Stevie Santana.
• Has run into Cain, albeit unknowingly.
