- Specifically, the massive battle near the end of the film, with Loki or Thanos being "the evil one".
- The Valley of the Damned is actually the Valley of Megiddo.
- The "master" referenced in a few songs is either Jesus or the Anti-Christ. Possibly, the army doesn't even know which side it's on (Our only master with fire and fury of hell will see his bidding done in Soldiers of the Wasteland).
- They believe that they'll rise from the dead when (The second age is coming/It's the dawn of a new day/Judgement stands before us/The second king will rise in Revelations). Jesus is the "second king", but he will never "rise" because he's already been defeated.
- They can fly because of the powers granted by their undead state. They cannot die because, obviously, they're already dead, having been defeated during Armageddon, but they can't rest because of their absolute devotion to the idea of defeating all evil.
- I had always assumed that they were riding on dragons.
- Alternitively, they are killed and ressurected over and over again (Screams of pain in death descending, rise again from Hell defending in Operation Ground and Pound.
- Proud and so glorious
Standing before of us
Our swords will shine bright in the sky
When united we come
To the land of the sun
With the heart of a dragon we ride
The "we" in here is the Varden. It is the opener for an epic battle.
Next we'll cover this stanza:
- We are flying on wings in winter sky
With fire burning deep inside
We are warriors of endless time forever and on
On wings of steel an ancient flight
We see the powers that unite
The gods will now send us a sign of battle once more
Through the valley we ride
Full of glory we soar
Where the fights will be raging
For now and for more
When united we come
And divided they fall
Tonight you will witness it all
Most of this song is about the final battle under Farthen Dur. The "we" in this part is Eragon and Saphira. The "valley" mentioned here is the huge valley of the Beor Mountains.
Adding to the above theory about Eragon: I believe that the song is about Inheritance. The Eldunari being almost literally hearts of dragons
This troper has a theory that Music/Dragonforce is the result of a project to build a time machine.
So this guy and his buddy are clearing snow off of a road in a pickup truck, when one pops a Dragonforce album in. Proof?
"Power through the ice and snow forever more" - they're doing their job
"Here we are the chosen ones we cannot fail now" - Well, people will be pretty annoyed if they don't clear the snow.
"Killing all the mortals down the winding road" - they're too busy rocking out to notice that they ran a few people over.
- Ok, this is the greatest piece of writing I've read today.
"Day after day as I bodies slay (...) The fallen ones and forgotten souls / Will rise up over the slain" - refers to Wights. The watchmen are fighting endless hordes of undead, and every fallen human will eventually join the Others' army.
"Rays of sunlight now are gone / Only visions of ice will remain" - The eternal night is coming and the world is slowly covered in ice and snow. Both of those happened during the period known as "The Long Night", when the Others conquered most of Westeros.
The song praises the "power of night warriors", while at that point Night's Watch consisted mostly of criminals forced into it. It also references "the almighty sword" - probably the Lightbringer, a fiery sword which was supposed to be wielded by the hero who will defeat the Others, but unfortunately "the flame has died forever" and there's no more hope. Finally "the master of all evil sign" may refer to the Great Other from the R'hlloran religion - the watchmen would be familiar with it, considering Stannis' army joining them at the end of A Storm of Swords.
- They are warriors from a different planet, that has since been destroyed in a major conflict. Their music is their method of coping with the loss and grief. The war had a long and elaborate history stretching centuries or even millennia, so their lyrics have diverse perspectives regarding the conflict at that moment, representing different points of view. The reason members constantly leave are because of arguments revolving around tossing blame, questionable justification, and general Survivor Guilt. The recruitment of new members is just a facade to keep up the "band" act.
- Give Me the Night is about addiction, and Seasons is about recovering from addiction.
