Progress
Finally, you've arrived... and discretely also. Good.

Hellscream allows our kind into Orgrimmar because we are still his fellow kin--he cannot turn his back on us, or we would become as pathetic as the humans who enslaved him. My point is: be careful. You can be powerful, but if you are foolish, then you are as good as dead.
