In the first actual hour of being on mission, of Nero's first ever actual mission, he had already faced off against a swarm of invisible, vapour curses and was now being attacked by, as far as he could tell, a curse that existed as a grating sound and targeted by endless darkness that was somehow alive - probably also as a curse.
The army life was nothing if not exciting. Instead of panicking at the rapidly deteriorating situation, Nero found himself feeling a little excited. He was standing on a razor's edge, and a single wrong move could cause not only his own death, but the death of his teammates. Ordinarily, something like that would scare or intimidate a person, but this was exactly what Nero had been training for all his life. Thousands of hours of studying, training, working hard and forcing himself to be diligent instead of relaxing had all been so that when such a moment came, he could excel.
