Dagger in the Dark Scenario

The Dagger in the Dark scenario with 5.2 the Throne of Thunder became available to Alliance. So of course I had to test it out. I must say it was much shorter than the A Little Patience that the Alliance got. I’m just curious does the Horde become humans when they play that one? Or is it Night elves? Or gnomes? Or dwarfs? If anyone plays Horde side let me know. My curiosity is nagging me about it.
