What's the 2 main difference between the 2 Accolade's

it actually says in the lyrics something like 'you will not have died in vain' so it's definitely a sequel.

I love both songs but I really like the athmosphere of II. When Russel comes in with 'on a cold and misty night....' truly magical that.

The atmosphere on i is much more laid back, I think.
 
The first Accolade is like a Mini epic song that is shorter than say DWoT song, and the 2nd make me feel like it's more of a "straight" forward song with some changes but not too far off its basic structure.
Mike Romeo would make a great dwarf, so let's go Romeo Tossing! :p
