Tengu blademasters are the epitome of martial pride and arrogance and they have reasons for it. They have studied the art of the blade for centuries if not millennia. Their techniques are faster than the human eye can follow, and they wield their weapons with such grace and precision that any swordmaster of Hoeth would be put to shame. Furthermore, thanks to their innate affinity with the blue wind of Azyr, many of these elder tengu have mastered the ability to see several seconds into the future, making them impossible to surprise and giving them even more advantage over their rivals. In combat these duelists command armies of followers whose sole purpose is to hold off the majority of enemies while the blademasters seek out enemy champions to duel and test their skills.
