The Crown Plot

This appears to be a letter from Arlon Bladeshaper to Karzov:

"Karzov,
If what you say about Gothwan is true, then we can no longer plan to smuggle the Crown out of Blacklake through the sewers. The Rats would certainly betray us and try to take it, and would probably succeed since the sewers are their home turf. You'll have to sit tight and hold out against Neverember's soldiers for a little while longer while I figure out another way to get the Crown out of Blacklake.
I know that you would rather I abandon the other plans I'm working on and just come to Blacklake personally. We've had this discussion before, and my answer is still the same. I'm working closely with our... other allies on these plans, and they wouldn't be happy if I abandoned them. And considering how much we need them right now, I want to keep them happy.
The Rats' betrayal, while we should have expected it, is an unfortunate delay. But if you can keep control of Blacklake until we can smuggle the Crown out of there, it will all be worth it. I will set the Crown upon my brow, and Neverember's lies will be laid bare for all to see. The Nashers will take control of all of Neverwinter, and we will reclaim the city's former glory!
For Neverwinter!
