My personal favorites were Destiny War and Federation of Fear
Destiny War FTW. It was AMAZING. I think I’ve listened to that ten times.
I really liked dark mirror and destiny war
and federation of fear RIP Carapar
Federation of Fear was probably my favorite.
Never had a chance of reading them in person 
I always liked Federation of Fear and Riddle of the Great Beings.
I kinda liked the Takanuva blogs. They were short but really helped us understand what the heck Takanuva was doing 2006-2008, and then why he was a huge Toa of Twilight.
Federation, probably.
Oh, wait-
Destiny War is definitely my favorite serial of the ones I have read so far. It had all of my favorite characters and masks, it was overall a very good serial.
I still have yet to read Dark Mirror and Federation of Fear, which I have heard are both very good.
Say whaaaaaaaaaaaaaaaaaat? 
Dude, you mind as well just see if you could even find them all. Seriously, there were like, 21? If you count the shorter stories. I recently printed them all out, and I’m super hyped to read 'em.
Could someone tell me where to find them.
Biosector01 has them on their site.
Federation of Fear.
Mostly because it’s the only one I ever read, but hey, it was good.
