Spoiler alert: I talk about Jintha'Alor in the Hinterlands.
I'm running around the corner to the altar area at the top and three thoughts go into my head in this order:
First: Damn, I bet those were the mobs I needed for the kill quest.
Second: Uh oh, are there Horde around who just killed them?
Third: Holy shit, that is a lot of sacrificed trolls.
I'm talking everywhere, dead trolls. The stairs are covered. The grass. The stones. Everywhere. All sacrificed.
You can read all the quests you want that talk of the savagery of the trolls, but when I went around the corner and see it, that's when it hit me.
So I starting thinking back about my troll lore, both distant and what my characters have actually seen, and I realized that trolls are absolutely frightening. The Scourge and Twilight cults have their suicidal tendencies and doomsday prophecies and horrors, but can they really compare? Those are all recent. New kids on the block. Fads. The cult of today and gone tomorrow. But the trolls, for them worshipping murderous gods, sacrifice, and torture, those are not isolated events. Those are tradition. There's cult and then there's thousand-thousand year old culture.
