Ever since Kyros merged with Calaminus and their memories became one, Kyros had already known the existence of guns.
But alas, they were practically useless in his specific situation.
In the battle against Destiny, their foes were always stronger. And with their resource, Kyros could only create guns that would kill a Champion at most. This was because, unlike the bow, which relies on the strength pulled back, the weapon had a set speed and power upon firing. They were basically weaker crossbows.
In comparison to crossbows, the crossbows of this world had a magical science behind them that allowed the strength of their string to be strong and could be strengthened. The same goes for bows. But for guns, apart from the rudimentary science that Kyros knew, he would have to 'invent' a magical science behind this to make it stronger.
Kyros could and had theories about how to do this, but he always had weapons and powers far stronger than guns.
