Grombrindal has no Fear!
(Rule)Description: The White Dwarf is Unbreakable. If his chosen unit breaks and flees, for any reason, he will always stand his ground. If the unit was engaged in combat, he will stand firm and continue to fight while his unit flees, denying the foe the chance to pursue. Grombrindal can even join a unit that is not Unbreakable, this is an exception to the normal Unbreakable rules.
