Author's Note: Even without this chapter, you are still receiving the entire story. I'll repeat that: You are still receiving the entire story. The extra chapter is merely a fun addition for true fans of the Mass Effect series.
Oh, did I say that out loud? Sorry, that wasn't directed at you. I was talking to the true fans behind you who were willing to pre-order the Collector's Edition sight unseen, and pay the ten extra dollars at launch.
You might say they give 110%.
Again, don't worry, it's nothing really important to the storyline, anyway. An added bonus, dude, and nothing else. It just involves the last living Prothean and a trip to Eden Prime. That's right, you heard me. The last living Prothean. No biggie. Just a remnant of the alien race the series has been referring to so heavily over the last three games. It's not like the Protheans have played a big part in the story. They're just the whole reason Shepard's on this quest to begin with—a quest that began on Eden Prime.
It's like I'm selling concentrated doses of nostalgia for, like, no reason.
I should probably end this note. I'm practically advertising this thing by telling you that you don't need it. And you don't.
Last living Prothean.
Eden Prime.
You don't need that.
Now, if you'll excuse me, I'm going back in time to sell Jolee Bindo as DLC for Star Wars: Knights of the Old Republic. He's not essential to the main storyline. Not at all. Trust me; I'm an artist and I've been to the internet.
Jolee's "Snake Story" is also sold separately.
Because why sell fond memories wholesale when you can piece 'em out?
