Baron Sablemane's Poison

Here, take this to your master. I'm sure that whatever the reason, Rexxar will put it to good use. Oh, and do be certain to remind him that he owes me. He knows what I want, and I'm certain that however he intends to obtain it for me, I'll be seeing you again sooner than you think. Now, do be a good little boy and run this up to Rexxar.
