In case you're curious, here's the scoop on Scarlet Cavaliers. Six (6) of them exist in all of World of Warcraft. All six of them can be found only in Mardenholde Keep, which is in Hearthglen, Western Plaguelands. They're pretty nasty, as they have a two second knockdown stun and use Mortal Strike and Cleave pretty liberally. Two of the six are easily soloable: * The first one patrols the ground floor of the Keep in the clockwise direction. * The second one patrols the second floor of the Keep in the counter-clockwise direction.
