Heilix, we can PM about it if you're really adamant about Gilford. I would be far more open to him being a Second Lieutenant, perhaps? We just need to come to an agreement/understanding about who he is, how many men he commands, why he's working in Kakariko when he's stationed in Castle Town, etc. Creating highly influential NPCs is something I [i]really[/i] need to know about before you post it. 

For future reference, the chain of command for the Hylian Army goes something like this:

(Rangers, Mages, Infantry, Guards, etc.)
Second Lieutenant 	
First Lieutenant 	
Captain 
Major (Sir Orca Halbert is here)
Lieutenant General 
General of the Hylian Army

Also-- I agree with Derv. I think jumping the gun on his Darknut would not only make little sense/be quite an overreaction, but it wouldn't mesh very well with what's going on story-wise right now. You have to build off what he's already posted. If it was really that obvious he was a Darknut, I would have pointed out that his character wouldn't have been able to so easily walk right into town or else had the guards react appropriately (like how Izzaz rode a Wolfos into town and Halbert later reprimanded Kaiver for letting it happen).
