The most common character template in Nepherasta has six parts: Appearance, Personality, Power (often including Spells and abilities, though if those lists are long they are sometimes separated,) Equipment, Way of Life, and History. It's a lot, but the more information you create for your character, the more rounded and fleshed out your character will become.
You're not limited by what you see here, add on whatever information you wish about your character.
