Thanks to a harsh life, Arryn Caverns knows how to take care of herself and provide her own means of survival. To this end she has garnered the knowledge and skills necessary to build a variety of gadgets, including a specialized prosthesis which she maintains herself. The one drawback is a slight limp which impedes her abilities in combat, and self-imposed imposture syndrome which she can't seem to shake. Additionally, thanks to the tremor present in both hands, delicate work is often impeded and her aim is often disrupted.

While Arryn Caverns will see a job through to its conclusion and put forward her best effort, it’s still just a job. Arryn Caverns's true loyalties lie to her friends, and through thick and thin,she will stand by them and die for them if needed. This loyalty is reserved for those who have earned Arryn Caverns's trust, putting her at odds with other Mercenaries that are only doing a job for the money. This also makes it harder for employers to trust her motives, often times creating extra competition and difficulty finding work. None of it matters to Arryn Caverns, though, because loyalty to her friends is not something credits can buy.

Arryn Caverns prefers to push the rules to the absolute limit. While she is unlikely to actually break rules or disobey orders, she toes the line between what is allowed and what isn't at every opportunity.

Despite an aversion for physical confrontation, Arryn Caverns has a quick-witted and sharp sense of humour, and never passes up the opportunity to make a quip or jibe about her situation, or to taunt her enemies. While some find Arryn Caverns to be funny and likeable, others do not always respond so warmly, and occasionally Arryn Caverns will get herself into more trouble than she thought when someone takes a joke the wrong way.

Sometimes the only way to prepare for the worst is to always expect it. Arryn Caverns takes this philosophy one step further by never leaving home without accounting for every possible scenario she might expect to encounter. Arryn Caverns tends to always have the right tool or item for a situation and has a habit of quietly and almost smugly presenting solutions before anyone even recognizes there is a problem. This foresight is far from infallible, however, and she often finds herself at a loss in situations that go beyond what she could have imagined. While incredibly practical and often a life-saver in a pinch, her perpetually pessimistic outlook on daily life can be a bit draining on more optimistic-inclined companions.

When Arryn Caverns gets in trouble, she finds no fault in bravely turning tail and getting the hell out of dodge. Obviously, this means that she tends to survive even the most deadly encounters... but the same can't always be said for her compatriots. This fact hasn't exactly made her the most popular among her peers, but hey, at least Arryn Caverns isn't dead yet.
