1: A portal to mystery (ep.6)
2: The order of the stone (ep.1)
3: The last place you look (ep.3)

Episode 6 has go to be my favourite because of its atmosphere and twist on the murder mystery...plus youtubers!

(and the entire episode is just awesome.)

The first episode is my second favourite episode because of the entire scene at Evdercon and in Ivors lab.

(Plus the bridge scene was really funny...)

And the 3rd episode was my third favourite because it's felt oddly weird and mysterious, and the quest to find Soren was really cool.

Plus, the name of it sounds just AMAZING.

(By the ways, number 4 would be probably be episode 2, or 7.)
