Where neither Seraphim nor raindrops go...
A character is more than a set of statistics, skills, and gear. Think about the background for your character, where they grew up, who they might know, and how they gained their skills. Describe the character’s appearance, any distinguishing features or commonly worn clothing. Envision something of your character’s personality, attitude, or how they might respond to certain situations. What do they love, enjoy, hate, or always do? What flaws might they have? Think about what makes your character unique and write something brief to describe them.
You don’t need to figure everything out, and some will come out as we play. They will probably even change, but it is good to a have some idea of just who it is you are playing!
