Katie is dim, affable, and curious. His home planet, Teta IV, is a matriarchal theocracy with a strict hold on it's residents. The culture integrates all of the citizens into the main religion, which, surprisingly, is far more forgiving than the actual society. It takes a lot for a citizen of Teta IV to escape Teta IV, but through money and family ties, the mercenary has achieved just that.
Generally, he doesn't follow his culture's socially acceptable norms, such as deep-seated xenophobia. He is deeply religious, but prefers to carry out his religious affairs in private rather than public, not even going so far as to pertain to religious clothing laws.
Vrischvu is Katie's religion, with the ruling goddess of Dezil. She preaches equality in all humankind and leading a virtuous life.
Equipment:
Katie's armor is made by his father's company; Brighton. They're big on quality and aesthetics. His armor by itself is lightweight - using steel, cloth, and other various metals. It does it's job as effectively as it can while remaining light, mostly protecting his chest and leg areas. The designs are custom and have a Celtic influence.
With him, he keeps a black bow. It seems standard - high quality, malleable, and expensive. A small white engraving is on the side of it - Brighton again. It leads one to believe all his equipment is manufactured custom.
He uses different arrows, most of them being capped or have barely detectable bristles.
