Since Moria east gate revamp is going on i tought this was the right moment to give a suggestion. What i was thinking was to add doors to the gate, first of all because it would be more lore accurate (you can find that information in the book, at the end of "the bridge of khazad dum" chapter), and also because it is weird that one of the most important location in Moria is so "open". It would also be more realistic to make to make them broken, considering the ruin and the orc invasion. I hope you will consider this
