So, Studying the Corrupt quest is an interesting quest with some good lore. In the quest, it's about the story of man called: Garoth, who tries to find a cure for the corruption. The quest is fairly interesting and it set me up to thinking the dungeon would be centred around corruption. But, from my understanding: Garoth somehow found Lost Sanctuary bridge, found the species living underneath the bridge and decided a great way to spread corruption is by enslaving animals? This dungeon doesn't make too much sense to me. If anyone has a better understand then please tell me.
