Hrm.. is it possible for a dwarf to be an assassin? I can't imagine one dressing in light armour, jumping from roof-top to roof-top, or being quiet for long periods of time..
Yes, Dwarfs actualy are the best assasins ((ERagon spoilers XD)) seriously, ive seen a group of a about twenty elves be killed by three dwarf assasins, Elf casualties:20 dwarf casualties:0
