Either way, he didn’t deserve to get tortured.
The smuggler in question was a He by the way.
Are you sure you read the book?
I don’t have a chalk board with crayons so I can only make this so easy. I’ll do my best though.
Alliance: Scared of Sylvanas and want her captured.
Anduin: Tells Alleria and Turalyon to capture Sylvanas by any means necessary.
Alleria and Turalyon: Capture a group of Horde civilians.
Alleria: Hears whispers from the Void (which has entities in it like Void Walkers, Void Wraiths, and most predominantly, Void Lords) that an orc who is a mom knows something.
Orc Mom: Refuses to say anything to them.
Turalyon and Alleria: Run out of patience and decide more drastic actions are required.
Turalyon: Uses chains of light to pin Orc Mom to the ground.
Alarya: Uses magic from the Void to invade her mind and extract information.
Forsaken Apothacary: Distraught over seeing Orc Mom get tortured that they helped a dark ranger and were all made to keep a vow of silence before she left, but he gives the information up anyway to keep Orc Mom from being tortured more.
This heavily implies that the entire group knew about the Dark Ranger, but the Void singled out the mother to Alleria deliberately. I wonder why.
This is the Void we’re talking about after all.
A Male Human Smuggler who has this done to him as well.
Now we can make claims that all of this is necessary to capture Sylvanas until we’re out of breath, but entities in the Void (Walkers, Wraiths, and Void Lords again) don’t really care about that. They’re just happy to see mortals using the Void to cause harm.
This is why I say that the Void, or for those who have trouble separating meaning from literal, Void Entities, are laughing as we use their evil power to fight another evil power.
