Envoy Icarius: Zarath, I am perfectly capable of making it up this road to Eclipse Point. If we do not deliver this missive, Lord Illidan will have both of our heads! You are dismissed!
Blood Lord Zarath: As you wish, my lord.
Envoy Icarius: Ah, sweet, sweet bloodthistle... Probably left behind by one of those filthy addicts at Eclipse Point.
Envoy Icarius: Their loss is most definitely my gain...
