Cavalier

While many warriors strive to perfect their art, spending all of their time honing their skill at martial arms, others spend as much effort dedicating themselves to a cause. These warriors, known as cavaliers, swear themselves to a purpose, serving it above all else. Cavaliers are skilled at fighting from horseback, and are often found charging across a battlefield, with the symbol of their order trailing on a long, fluttering banner. The cavalier's true power comes from the conviction of his ideals, the oaths that he swears, and the challenges he makes.

Cavaliers tend to marshal forces on the battlefield, using their mounted talents and challenges to control the flow of the fight. Outside of battle, cavaliers can be found advancing their cause through diplomacy and, if needed, subterfuge. The cavalier is no stranger to courtly intrigue and can hold his own in even the most delicate of social situations.

In Azeroth, Cavaliers are the Knights of Stormwind and the Kodo Riders of Thunderbluff and Orgrimmar. They are also Blood Elves that couldn't make the cut for the Blood Knights, and, in a wierd strange sort of way, Worgen -- especially with horses being skittish about wolves and werewolves in particular.

Amongst the Alliance
Cavaliers existed as long as there was Chivalry amongst the humans. Chivalry was an invention that meant to civilize the knight and give him a purpose other than just God and Country. The Courts of Love in Lordaeron and Stormwind were invented so that Chivalry could have an added dimension. And that is Romance.
