Will the GM be making a character?

If you'd like some advice on what kinda character to make, why not just aim to fill in the gaps in the cast so far? We don't have a emotionally grounded character yet, or a straight up melee fighter. It helps if you visualize their wish before delving into their magical abilities, as what their wish is like and what emotions they experience during it basically determine what kind of magic and weaponry they have at their disposal.
