Well, it depends on what you mean by my world. John and Dave are from "my world" but they were trained differently than I am, and Dave was trained much more extensively than your average human. Troll society is centered around war. We're a really violent race, and you have to survive the trials before you can even receive a lusus and a hive. Depending on where you're at in the hemospectrum, there will always be people trying to kill you, but it's for different reasons. And as an adult, we would all go off into space and conquer other planets and races, so you had to be fully battle ready before you reached adulthood. It was mostly up to you to learn the skills you needed yourself though, especially because there wasn't really a common weapon everyone used. Some weapons were more popular than others though, and my weapon, sickles, were used by the threshecutioners, so I had some help watching their moves online and in movies and shit.
