I was looking over Abramac and he is hitting a grey area with the regional language thing. The problem with having Tritower as your place of origin is the regional language is still Low Landellian. So, although it's technically not Venza, it's more or less equivalent for purposes of the regional language. (I suppose that could be clarified up front, my first character has no regional language, either.)
Feel free to adjust as you like--you seem to have so many languages in your future the regional seems a minor issue, IMO, but I'll leave it to you.
The rest of the character seems rather good, particularly since the previous review was so complete.
