Quiet and usually located off to the side rather than in the center of a room, Kallum, or Arkys as he is more commonly known as, is not a particuarly sociable person and rarely speaks to strangers unless spoken to first. His quiet attitude isn't necessarily because of shyness but, instead, usually because he doesn't have much to say or add in most conversations and he isn't interested in small talk. That being said, while he may not be talkative, Arkys is sharp and perceptive of the things around him. He's naturally observant, an excellent listener, and remarkably good at rememebring what he is told down to the detail. These traits came in handy during his days in the Amovian military when he spent several years following orders, keeping to himself, and knowing when to not speak out of line to avoid punishment. However, Arkys' reserved personality can sometimes come at a detriment when he retreats a little too far and becomes emotionally uncommunicative and bottles up more than he should. Coupled with his tendency to be vague and dismissive towards others who try to pry too far into what's on his mind, he can become frustrating to talk to, work with, or help out. He's been trying to work on being more emotionally open with those close to him, but he still has a ways to go. Arkys is typically seen wearing either his full armor or just his helmet with his casual attire. His head is almost always hidden away within his helmet to protect his identity from prying Amovian eyes, affecting the way he generally emotes in conversation. Rather than rely on facial expressions that can't be seen, body language, hand gestures, and verbal tone play much bigger roles in Arkys' communication. When he is not wearing his helmet, his antennae also move around in response to his emotions.

Arkys is someone who can be described as 'honest to the point of bluntness;' he does not have much of a filter and isn't interested in dancing around information unless the topic has to do with himself. He usually prefers to do things, whether it be work, conversation, or any other task at hand, as quickly and efficently as possible. When out on bounty missions, he likes to get things done quickly and move on rather than taunt, banter, or play games with his target. His even-temperment helps him with having a strong grip on his emotions, rarely ever letting them spiral out of control. Going about things with thourough planning and logical reasoning are far more familiar and comforting for Arkys rather than acting on risky 'impulse' decisions. However, should an unexpected event take him by surprise and force him into a position where a snap-decision is required, he will begrudingly rely on whatever his gut instinct and prior knowledge tell him to do, even if it leaves him feeling sick with uncertainty. While Arkys is good at keeping his feelings in check, his grip is not without flaw. He's not above holding grudges against others and first-impressions can play a role in him immediately distrusting someone based on offputting vibes. It also means he still has a temper that can be set off, even if it isn't the easiest thing to do. Should someone/something of great importance and value to him be taken away or harmed, or if his lengthy patience is finally exhausted, his iron grip can be loosened and give way to a consuming mixture of anger, panic, or fear. Those moments are not often very proud ones for Arkys.

To the few that Arkys is deeply close with, his personality is warmer and more open compared to how he is with strangers. While he still isn't the most animated and talkative person, his inner passion and enthusiasim for the things and people he loves shines brighter and clearer. He tends to fixate on things, and when he's fixed on anything in particular, whether it be a new movie, a game, a scientific fact, etc., he will go out of his way to learn all he can about this new thing and share (or 'infodump,' as some jokingly say he is guilty of) whatever he learned with those close to him. On top of being more open with his "sillier" fascinations and curiousities, he is someone who tries to show his love and care through quality time and actions more than words. For example, his observant nature and good memory are well-utilizied when he is giving gifts to those close to him, often remembering small and obscure things his receivers like or have a preference for and wanting them to know he listened and remembered. If someone he is close to is in need of comfort, he prefers giving them a gentle embrace to let the gesture speak for himself over saying something to them. When Arkys is on the receiving end himself, hand-made crafts and things that were made by his gifter, rather than by someone else, hold far more value and meaning to him.

Another aspect of Arkys that becomes much more apparent the closer someone is with him is his unshakeable loyalty and sense of honor. He follows something adjacent to a "knight's code," discouraging him from using underhanded tactics and encouraging fairness in the pursuit of enacting and maintaining justice. This applies both to situations that require him to engage in battle with another, and in more social situations where secrets must be kept, trust must be honored, commitments must be followed-through with, and the like. Betraying his loved ones is an act so dishonorable to Arkys, he would rather risk his life than put them in harm's way. The reason why he was so violently shaken to the point of sickness when he finally realized he had been fighting on the side of oppression and injustice during his years in the Amovian military was because his original motivation was to help, protect, and aid the people of Xeria. As it turned out, he was a victim of the lies and disinformation Amovia had fed him and his family since childhood and he had been doing the opposite of helping. Learning of that reality shattered both his code and Arkys himself, leaving him to pick up the pieces and not only attempt to come to terms with his past misdeeds and the severity of what he had contributed to, but to also rediscover who he is, what he now wants to be, and where he wants to go from here with the new life he hopes to lead.
