Stopping by, months after the fact, to say this thread (and Solvynt’s work especially) is pretty mind blowing! There can’t be many places outside TYFTH that would have managed this much info.
I can’t add much more right now, but I remember Alek mentioning that Vengeance’s ‘When my work is finished, I’m coming back for you’ is from Warcraft 2: https://www.youtube.com/watch?v=BBViA9draOs
