Who exactly was a clan leader? what were a clan leader's duties? can anyone become a clan leader? how does one know if they're worthy of being a clan leader? Night's head was filled with such thoughts but when he looked at Nate, all of them seemed to have been for naught, he didn't understand what he felt but he knew that Nate was the perfect fit, the best option for the clan leader position.
A clan leader was someone trusted and someone who could handle everyone without any issues, he/she knew what was the best course of action to take most of the time, their duty was in the name of the position itself, a clan leader's duty is to literally lead the clan. Naturally, not everyone can lead a clan, or even lead, while some lead through experience, some lead through their instinct and feeling.
