Not a typo, but P. 82 looks unbalanced layout-wise with its single column of text to the right. I realize this is probably due to lack of text, but maybe the graphic below can be altered or added to a little to compensate? Or even more text written? Should be enough with a paragraph or two - mabye about an additional location by the East-Gate? We'll never tire of more material
On P 83, I'm confused by the sidebar about the gates, and especially by this part: "However, when Thrór II came to Moria in 2790, he found “the Gate was open.” Does that mean the gates could have been closed when Thrór arrived?"
I'm guessing "Thrór II" should be just "Thrór" - and then the second "Thrór" should maybe be "Thráin II"? Otherwise - how could Thrór find the gates both open and closed at the same time?
Below, there is a suggestion that the gates could have been destroyed in the retreat from Moria - but how could that be if Thrór found the gate "open" in 2780? I guess "open" could mean "destroyed", but I'd suggest rephrasing parts of the sidebar for clarity.
