As promised, here is an example sheet to show how a character sheet for this roleplay would look like. While it is a bit more involved than some play-by-post character sheets, at the end of the day it all comes down to right numbers at right places. The formatting can be different, of course, if you feel like it's easier to read in some other way. At the end of the day, what matters the most is that the character shine through rather than how the sheet itself looks.
Here is the link to the Google Doc version of the sheet.
Just remember that this is a rather straight, no-nonsense example of a character just to show you how a 'ready' character would look like., Please aim for a less generic and more unique and interesting stuff than what the GM has done here!
