I'm 99% sure the chevron gets transfered from the 1st to 2nd senario.Also in the 2nd scenario, upon completing the quest you receive another special sign (can't remember the symbol).
So if you import from 1 to 2 to 3 you also keep the signs to show your exploits, and in Wiz 3 you also get a sign (think is it a * according to the endgame text which joggled my memory).
So if you have all 3 signs, then you are truly a hero and you can proclaim to be a Wizardry master
Unfortunately, I don't know the hex where it is, isn't it just plastered over the last character of your name (max. 15 chararters?)? or is it extra bytes?
