Zep is a dangerous irken to cross paths with, which should be a given for someone who leads armies across the battlefield and enemies to their demise. Strategic, observant, and impossible to read. Everyone's transparent and open like a book through their eyes, while to others they're as thick as a brick wall and there's no way to tell what goes on behind those eccentric eyes and plastered smile.
Despite being awfully creepy with the way they always smile while threatening to tear your PAK to pieces over small mishaps, there's something alluring about them that makes people follow them. Some claim it's because they're scared and fear what will happen if they fuck up, but others say it's because it makes them excited and they want to be noticed and praised. Either way, his record of leadership and success is ideal, so the Tallest let him do whatever he pleases.
