Repanse de Lyonesse won fame as the dreaded Damoiselle de Guerre who rallied the battered armies of Bretonnia during the kingdom's darkest hour. This was when King Louis the Brave was slain in battle before Couronne fighting a vast Chaos horde invading Bretonnia from beyond the Sea of Claws. Louis' army was all but destroyed. Couronne was besieged and to make matters worse the king's heir was still a child unable to lead the nation.[1a]
