This game mostly uses D12, but during character creation you'll need some others as well.
Use Paint to draw a picture of yourself in the oval space and a coat of arms for yourself on the shield. It doesn't have to be fine art -- something simple will suffice, but please feel free to be as simple or elaborate, or as silly or serious, as you like.
Also, roll up your stats using this table:

Fill in your name, your race and your stats (from the table above) onto your character sheet (into both the Start and Current sections).
Once you've done this, let me know your stats and I will tell you how to fill in the rest of the sheet.
