Scarlet Quartermaster

The Scarlet Quartermaster is a human vendor found at the eastern end of the Darkmoon Faire's Zoo Bizarre on Darkmoon Island. She claims to be a member of the Scarlet Crusade and sells various Scarlet-related transmogrification items, apparently in an attempt to raise funds for the crusade. However, she will only sell her goods to players who are wearing the Tabard of the Scarlet Crusade or the Cropped Tabard of the Scarlet Crusade.

Quotes
Interlopers like you are responsible for gutting the strength of the Scarlet Crusade! We would've eradicated the unliving from this world and the Burning Legion would have never come this far! Begone!
 * While not wearing the Tabard of the Scarlet Crusade or Cropped Tabard of the Scarlet Crusade

I can see you're a friend of the Crusade. I've managed to smuggle some equipment out of the Monastery in an attempt to raise funds for our order. We will not rest until the unliving have been driven from Azeroth!
 * While wearing the tabard

Do keep in mind you and your ilk have left us on the verge of ruin, so what I'm selling won't come cheap.

I suppose you'll just have to trust me, won't you?

Unliving scum! Your very existence is an insult to everyone who lost their families to the scourge. Take that tabard off and crawl back into your grave before I put you there!
 * While wearing the tabard and playing a Forsaken
