Sword lords are those people that have finished training at one of Brevoy’s most elite weapon schools. Trained in the Aldori weapon style founded by Sir Sirian Aldori after his return to the country, you are one of the most able swordsmen in whole of Avistan.
Sword lords are a combination of fierce warriors and lithe duelists, knowing when to favor defense and leger-de-main, and when to use brutal combat force. Most of them use a combination of offensive and defensive styles, throwing foes off guard by switching between them erratically. When facing a foe in one-on-one combat, hope he does not know the Aldori fighting style.
