In answer to the version of the DotA map we play (and no, sixphere, it is not 5.84b), it is currently DotA Allstars v 6.30b, which I think is a little buggy.
I am surprised, I thought everyone would recognise the voice of Mortred the Phantom Assassin (see annoying animated gif on the left), which is based on the Warden in Warcraft 3. Here are some of her other quotes.
"I am the iron hand of justice."
"Let the hunt begin."
"I can taste their fear."
"Justice shall be swift."
"They shall not escape!"
"Let justice be served!"
"I am the law."
I have to say that my favorite quotes are from the two-headed Aggron Stonebreaker the Orge Magi, who says:
Head 1: "I'm with stupid."
Head 2: "Me too!"
And the quote from Slithice the Naga Siren, who says:
"Would you like to feel the ocean spray in your face? (spits)"
