The summary at the start neglects to mention you taking player actions. (It just says your King acts before you do. Then play passes.)
Determining attacking and attacked territories: You she mention again that ties are decided by the active player. If I'm reading this right, the territory with the most of your armies take precedence for determining battle location. (So even if there is a very weak opponent in another place, I'll attack based on where I have most.) That might be spelled out.
You might also add something about attacking neutral territories/those with no armies. Presumably you just move all your armies in?
Build Castle: The part about drawing the top card could be moved up since it is a decision the player could make at the beginning.
If you give a gold coin to another player, do you physically take their resource or just gain the ability to use it like in 7 Wonders?
This section should mention that you can only have one of each of the basic types.
If you already have a walls, for example, can you build a new one to replace the existing one?
Removing card types from the game: "Once all players have built one of the basic card types..." is ambiguous. It could mean that I build walls, you build a tower and entries. You should also forward reference the information on the next page.
Do you go through the deck and remove them or just when they come up? Presumably you replace removed cards from the display.
Produce a resource: "No more than two resources can be produced on a territory at a time.": Does that mean you can produce more on a subsequent turn, or it can only hold two total?
How do we as a player get the resources? Or do you spend resources off the board from placed you control? If a land is conquered, do the resources change owner?
Increase tensions: At some point it is possible that you've used all your own tokens. Does that mean you can't take this action anymore?
Special actions: These cards should be described somewhere. As it is, we have no idea what they do.
Examples of some of the sections would be a welcome addition.
