Jack Barricade's Clues

I'm going to try to upload as much of Jack's text as possible, because his is the most relevant to what we'll find inside the keep. I can't upload everything because that's somewhere in the magnitude of 350 screenshots.

So...

• It talks about stone golems. Initially, we assumed this was a reference to Crimson Guardians, but it seems much more likely this is the giant statue we saw in the new screenshots. After all, guardians aren't really big enough to carry Jack off, whereas this new statue could easily cart him off in the manner described.
  
• 4 Grandmasters, attack on NLC, etc. The purpose of the PQ will likely be to stall the attack on NLC. If we're just stalling rather than flat out stopping, that gives an excuse for it to be repeatable.
  
• Grandmaster Mage is female, as specifically mentioned there.
