Treel sees himself as the control subject in the science experiment called life. Often labeled as "boring" and "predictable", Treel keeps his wild and experimental side reserved for pet projects. This boring lifestyle leads to him being considered anti-social and when he does join others, instead of relaxing he prefers to keep quiet and observe.

When Treel does things, he makes sure everything is done correctly, no matter how long it takes. This means there are frequent delays in Treel's work, but it's usually done right, at least.

Despite his line of work, Treel still sees himself as a refined gentleman and will often put on a show of being haughty and arrogant to those he does not know. Treel only lets the mask slip to show his more laid back nature to those he trusts. To those he dislikes, he will actually become even more insufferable as taunts and quips without any regard for who or what he might be offending.

Treel considers his work to be the most important aspect of his life. This borderline obsession with the "job" leaves little room for any kind of personal or social life, making it difficult for Treel to relax and enjoy spending time with others. He excels in activities that relate to their work, but the idea of work-life balance is an altogether abstract concept.

Treel will never go into any situation head-on. Whether it be combat or just strolling down the street, he will stick to the shadows or cloak themselves in the Force. The less they are seen the better. If they cannot sneak up on someone, then Treel will not bother confronting them.

Treel may wear a lightsaber at his waist, but he always goes for his trusty blaster instead, preferring to shoot it out from range rather than trying to get in up-close and personal. Only as a last resort will he go for his lightsaber.
