Zax hails from just the other side of the far, far, far, far east, where the real dwarves (ie gnomes) hold sway. He has little time for the petty whims of humans, thinks hobbets are only useful as doorstops, cant abide elves; and dont even talk about those 'other' stunties that have the audacity to refer to themselves 'dwarves'.
All this can be put aside however (at least in the short-term) if there is a little gold to be had...
