How much of Darksiders do I have left to play?

I've been trying to beat this game for several weeks now but once I get in something always comes up and I just want to sit down and finish it once and for all until I play it again.

I just forged the...Arcane sword? Armageddon sword? Whatever it was called, it has escaped my memory but how much do I have left to play so when I have x amount of time I can sit and finish in one swoop.

No spoilers please as the game is awesome and can't wait for Darksiders 2 now.

EDIT: And it's the Armageddon Blade, I looked it up to be sure.

Is that after the dungeon with all the mirrors? That is where I stopped.

@ImmortalSaiyan: That dungeon was terribly long, and yes, you have to do a quest for the blade after that dungeon, fun boss, terrible temple.

Very, very near the end. Like a half-hour left if that.

@TentPole: Alright thanks for letting me know, just want to see the ending already.

You literally just have to walk to the last boss and fight it.

Last boss is a pushover.

@Guided_By_Tigers: Really? That's sad to hear, I will say the hardest boss for me was the bat, I just couldn't figure out the bosses tells during the fight. Maybe now it would be different as I am better at the game.
